What is tissue forcep?

Tissue forcep is also called allis forcep. Allis forceps are lighter on tissue compression than vascular forceps, so they are generally used to clamp soft tissue and are not easily slipped. If clamping traction is removed from the lesion to facilitate the surgery, clamp the gauze pad and subcutaneous tissue at the edge of the incision to avoid contamination of tissue within the incision.

Tissue forcep should be made of 20Cr13Mo or 20Cr13, 12Cr13 as specified in GB/T4237.

Feature of tissue forcep

a. Allis forceps should have good elasticity and firmness.

b. Rat tooth forceps should be heat treated, its hardness: 20Cr13, 20Cr13Mo for 40 ~ 48HRC; 12Cr13 for 32 ~ 43HRC, the difference between the two pieces of hardness value should be no more than 4HRC.

c. The opening and closing of tissue forceps should be easy and flexible, with no jamming and obvious swinging of the cheeks.

Type of tissue forcep

The depth of the front teeth of the clamp is divided into two kinds of damage and no damage.

a. Clamp with deep teeth is a damage tissue clamp. The clamp is firm and strong, not easy to slip, and is used for clamping soft tissues and flaps such as clamping traction of the lesion site being removed. It facilitates the operation, clamping the gauze pad and subcutaneous tissue at the edge of the incision to avoid contamination of tissue within the incision.

b. The shallow teeth are non-invasive tissue forceps. It can be clamped to close the blood vessels, and its pressure on the tissue is lighter than the vascular clamp.

Use of tissue forcep

The use of tissue forceps is basically the same as hand vascular forceps, but when released, you should use the thumb and index finger to hold the tissue forceps ring mouth, the middle finger and ring finger block the other ring mouth, and the thumb and ring finger gently force against the top.

Note that the tissue clamp should not hold the skin, intestinal tube, etc., to avoid tissue necrosis. When stopping bleeding only buckle on, two teeth can be, to check whether the buckle lock is out of order, sometimes the clamp handle will automatically release, causing bleeding, should be alert.

When using you should check whether the two pages of the transverse tooth groove of the head of the forceps are anastomosing, not anastomosing is not used to prevent the tissue clamp holding tissue from slipping off.

Use of common laboratory surgical instruments

Surgical instruments commonly used in animal experiments include scissors, scalpels, forceps, tissue forceps, needle holders, suture needles, vascular clips, etc. Most of these instruments are human surgical instruments, except for a few that are specially made according to needs.

Allis forceps

A. Scalpel

The scalpel handle and blade are made up of two parts: the handle and the insertable blade. The handle is usually stored and sterilized separately from the blade. The blade should be mounted with a needle holder and should not be operated with bare hands to prevent finger cuts. When loading the blade, hold the front back of the blade with the needle holder so that the notch of the blade is aligned with the flute at the front of the handle and can be loaded by pulling backward with a little force. To remove, hold the blade with the needle holder on the back of the tail end of the blade and lift the blade with a slight force and push it forward to remove it. The scalpel is mainly used to cut tissue, and sometimes the end of the handle is also used to bluntly separate tissue.

There are four types of scalpel execution methods as follows.

a. Bow-holding. Most commonly used, with a wide and flexible range of motion and force involving the entire upper extremity, mainly at the wrist. It is used for longer skin incisions and incisions of the anterior rectus abdominis sheath, etc.

b. Pen-holding. Gentle force, flexible and accurate operation, used for short incisions and fine surgery, such as dissection of blood vessels, nerves, and incision of the peritoneum, etc.

c. Grip style. Hold the knife handle with the whole hand, with the thumb and index finger squeezing the knife handle at the indentation. This method of knife control is more stable. The main movable force point of operation is the shoulder joint. It is used for incisions with a wide cutting range, thick tissue, and high force, such as amputation, tendon incision, longer skin incision, etc.

d. Reverse picking style. A conversion form of the pen-holding style, with the knife blade picking upward to open.

B. Surgical scissors

Surgical scissors are divided into two categories: tissue scissors and wire scissors. Tissue scissors are thin, sharp, straight, and curved two types mainly used to separate, dissect and cut tissue. Wire scissors are mostly straight scissors, and are divided into wire scissors and wire removal scissors. The structure of the thread removal scissors is characterized by a blunt concave page and a sharp and straight page. The correct posture of the shears is the thumb and ring finger are fastened into the two rings of the scissors handle, the middle finger on the handle of the scissors ring finger, and the index finger pressed at the axial joint to play a stabilizing and guiding role.

C. Vascular forceps

Vascular forceps are instruments mainly used for hemostasis, so also known as hemostatic forceps, can also be used for separation, dissection, and clamping tissue, and can also be used for traction sutures, pulling out suture needles, or used in place of forceps. The forceps should not be used to hold the skin, organs, and more fragile tissue, do not fasten the wheel teeth on the handle of the forceps, so as not to damage the tissue. Clinical vascular forceps have many types, its structure is characterized by a smooth front end, depending on the bed of teeth can be divided into a curved, straight, right angle, curved, with teeth, no teeth, etc., the handle of the forceps have a locking forceps teeth groove. Small hemostatic forceps are also known as "mosquito clamps".

The correct enforcement of the vascular clamp is the same as the surgical scissors, should avoid the wrong method of clamping. Close the vascular clamp, the same action of both hands, open with the thumb to hold the vascular clamp a ring mouth, middle finger and ring finger to hold the other ring mouth, the thumb and ring finger gently force against the top, can open.

D. Tissue forceps

Surgical forceps are used to hold or extract tissues for separation, cutting, and suturing, and also to hold sutures or dressings. There are many types of forceps, and the tips of forceps are divided into those with teeth and those without teeth (flat forceps).

a. Toothed forceps. They have teeth at the front end and are used to lift tough tissues such as skin, subcutaneous tissue, fascia, tendon sutures, plastic surgery, and other fine surgeries, which have certain damaging effects on tissues.

b. Non-tooth forceps. The flat front end, with no hook teeth at the tip is pointed and flat, and is used to hold tissues, organs, and dressings. Toothless forceps have lighter damage to tissue and are used for clamping fragile tissues and organs. Pointed and flat forceps are used for the clamping of fine tissues such as nerves and blood vessels.

The correct forceps holding position is thumb to index finger and middle finger, holding the middle of the two forceps feet and holding the tissue stably and moderately. The wrong forceps hold not only affects the flexibility of operation but also does not easily control the strength of clamping.

E. Needle-holding forceps

Needle-holding forceps, also called needle-holders, are mainly used to hold suture needles to close tissues, sometimes also used for instrument knotting, and their basic structure is similar to vascular forceps. The basic structure is similar to that of a vascular clamp. It is stable for holding suture needles and is not easy to slip off.

F. Suture needles

Suture needles, referred to as suture needles, are instruments used for the suturing of various tissues. There are three types of needle tip shapes: round, triangular, and spatula; and three types of needle body shapes: sub-circular, triangular, and spatula. Clinically, suture needles are classified into straight, semi-curved, and curved needles according to the presence or absence of curvature between the two points of the needle tip and the needle tail; and into angular and circular needles according to the shape of the needle tip cross-section.
