Description

Technical Field

[0001] The utility model relates to the technical field of tissue forceps, in particular to a novel cartilage tissue forceps. Background Art

[0002] Cartilage tissue forceps is a medical device specially used for cutting and repairing cartilage in surgery. This instrument is made of high-quality stainless steel material, which has good corrosion resistance and durability, ensuring stable and efficient work during surgery.

[0003] Rhinoplasty is a common plastic surgery, in which the angle adjustment and fixation of the septum graft is the most time-consuming and requires the cooperation of assistants.

[0004] At present, the existing cartilage tissue forceps cannot fix the cartilage well during the operation, and are prone to slippage and displacement, resulting in repeated adjustments of the graft, increasing trauma and delaying the operation time, prolonging the intraoperative anesthesia time, and increasing the surgical risk. Utility Model Content

[0005] The utility model aims to solve the shortcomings of the prior art that cartilage cannot be well fixed, slippage and displacement are prone to occur, and the graft is repeatedly adjusted, which increases trauma and delays the operation time, increasing the risk of surgery, and proposes a new type of cartilage tissue forceps.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A novel cartilage tissue forceps, comprising:

[0008] The main clamp arm and the auxiliary clamp arm are hinged by a pin shaft, a solid needle body is fixedly provided on one side of the front end of the main clamp arm, and a hole groove is opened on one side of the front end of the auxiliary clamp arm close to the solid needle body, and the hole groove is adapted to the solid needle body.

[0009] In a possible design, clamp ears are fixedly provided at the tail ends of the main clamp arm and the auxiliary clamp arm, and silicone pads are fixedly provided on both sides of the inner walls of the two clamp ears.

[0010] In a possible design, two connecting blocks are symmetrically arranged next to the clamp ears on the side where the main clamp arm and the auxiliary clamp arm are close to each other. The two connecting blocks are respectively located at the top and the bottom and are fixed with latch teeth, and the two latch teeth are adapted to each other.

[0011] In a possible design, a same spring sheet is fixedly provided on the side where the main tongs arm and the auxiliary tongs arm are close to each other.

[0012] In a possible design, the front ends of the main clamp arm and the auxiliary clamp arm are detachably provided with a same protective cover.

[0013] In a possible design, the diameter of the solid needle body is about 0.5-1 mm and the length is about 0.3-0.5 mm, and the needle tip of the solid needle body is about 0.2-0.3 mm long.

[0014] In a possible design, the main clamp arm, the auxiliary clamp arm, the solid needle body and the clamp ears are all made of nano stainless steel material.

[0015] In the present application, when starting to use it, the medical staff inserts two fingers into the two clamp ears respectively to pick up the tissue forceps, then removes the protective cover, and then designs and selects the cartilage tissue with appropriate shape, angle and size according to the patient's nasal condition, and then extends the tissue forceps into the cartilage tissue that needs to be removed and places the front ends of the main clamp arm and the auxiliary clamp arm on the left and right sides of the cartilage tissue, and then adjusts the front end angles of the main clamp arm and the auxiliary clamp arm according to the required position and angle of the cartilage tissue, and then pinches the two clamp ears, and while the clamp ears are pinched, the main clamp arm and the auxiliary clamp arm are driven to move in the direction of approaching each other through the pin axis, so that the front ends of the main clamp arm and the auxiliary clamp arm are synchronously moved in the direction of approaching each other, and while the front ends of the main clamp arm and the auxiliary clamp arm are moving in the direction of approaching each other, the needle tip part of the solid needle body limits the position and angle of the cartilage tissue, helping the doctor to fully expose and fix the shape of the cartilage. After the front end of the main clamp arm and the auxiliary clamp arm clamp the cartilage tissue, the spring sheet is compressed, and the teeth on the two connecting blocks are engaged, thereby limiting the position of the main clamp arm and the auxiliary clamp arm, so that the clamping force on the cartilage tissue remains unchanged, ensuring that the main clamp arm and the auxiliary clamp arm will not accidentally open during the operation, causing the cartilage tissue to fall off. Then the medical staff holds the tissue forceps to remove the cartilage tissue and then sends it to the position where it needs to be transplanted. After the cartilage tissue is sent to the designated position, the two clamp ears are first pinched to disengage the teeth on the two connecting blocks. The elastic principle of the spring sheet provides a certain tension when the main clamp arm and the auxiliary clamp arm are opened, thereby pushing the main clamp arm and the auxiliary clamp arm to move away from each other, so that the front ends of the main clamp arm and the auxiliary clamp arm are opened, and at the same time the solid needle body is detached from the cartilage tissue, so that the cartilage tissue is in the transplantation position, and then the tissue forceps are taken out to complete the transplantation of the cartilage tissue.

[0016] The utility model has the following beneficial effects:

[0017] The utility model provides a solid needle body, and the front end angles of the main clamp arm and the auxiliary clamp arm are adjusted according to the required position and angle of the cartilage tissue. When the front ends of the main clamp arm and the auxiliary clamp arm move toward each other, the needle tip of the solid needle body can limit the position and angle of the cartilage tissue, so that the position and angle of the cartilage required in the prosthetic rhinoplasty can be accurately fixed, which can help the doctor to fully expose and fix the shape of the cartilage, making it easier for the doctor to design the shape and size of the cartilage according to the nose shape of the customer during the operation, effectively ensuring the fixation of the cartilage during the operation, facilitating the doctor's operation and improving the efficiency of the operation, and at the same time effectively protecting the removed cartilage and tissue parts, reducing tissue damage and contamination caused by repeated operations during the operation, and improving the patient's recovery and satisfaction.

[0018] The provision of the silicone pad in the utility model not only increases the comfort of holding, but also prevents slipping during use, thereby improving the stability of operation. The provision of the protective cover can cover the front ends of the main forceps arm and the auxiliary forceps arm and the solid needle body when the tissue forceps are not in use, thereby preventing accidental punctures and preventing the needle body from being damaged.

[0019] In the utility model, the solid needle body has a diameter of about 0.5-1 mm, a length of about 0.3-0.5 mm, and a needle tip length of about 0.2-0.3 mm, so that the solid needle body can accurately clamp cartilage tissue without causing excessive damage thereto.

[0020] The utility model can accurately fix the position and angle of the cartilage required during the operation through the provision of a solid needle body, reduce tissue damage and contamination caused by repeated operations during the operation, and improve the efficiency and safety of the operation.

On the front end side of the main clamp arm 1, a solid needle body 8 is fixedly set, and a hole groove 9 is opened on the side of the front end of the auxiliary clamp arm 2 close to the solid needle body 8. This hole groove 9 is compatible with the solid needle body 8. When the main clamp arm 1 and the auxiliary clamp arm 2 are closed, the solid needle body 8 can be inserted into the hole groove 9, which can prevent the needle tip of the solid needle body 8 from being exposed, protect the needle tip and reduce wear.

[0030] The tail ends of the main clamp arm 1 and the auxiliary clamp arm 2 are fixedly provided with clamp ears 3, and silicone pads 301 are fixedly provided on both sides of the inner walls of the two clamp ears 3. The setting of the silicone pads 301 not only increases the comfort of holding, but also prevents slipping during use, thereby improving the stability of operation.

[0031] On the side where the main clamp arm 1 and the auxiliary clamp arm 2 are close to each other, next to the clamp ear 3, we symmetrically set two connecting blocks 4, which are respectively located at the top and the bottom, and they are both fixed with latch teeth 401. When the main clamp arm 1 and the auxiliary clamp arm 2 are closed, the two latch teeth 401 will bite into each other, thereby further locking the positions of the main clamp arm 1 and the auxiliary clamp arm 2 to ensure that they will not open accidentally during operation.

[0032] A spring sheet 5 is fixedly arranged on the side where the main clamp arm 1 and the auxiliary clamp arm 2 are close to each other. The spring sheet 5 can provide a certain tension when the main clamp arm 1 and the auxiliary clamp arm 2 are opened, so that the operation is smoother.

[0033] In order to protect users and patients, a detachable protective cover 7 is provided at the front end of the main forceps arm 1 and the auxiliary forceps arm 2. When the tissue forceps are not in use, the protective cover 7 can cover the front end of the main forceps arm 1 and the auxiliary forceps arm 2 and the solid needle body 8 to prevent accidental punctures and damage to the needle body.

[0034] The diameter of the solid needle body 8 is about 0.5-1 mm, the length is about 0.3-0.5 mm, and the length of the needle tip is about 0.2-0.3 mm. Such a size design enables the solid needle body 8 to accurately clamp cartilage tissue without causing excessive damage thereto.

[0035] The main forceps arm 1, the auxiliary forceps arm 2, the solid needle body 8 and the forceps ears 3 are all made of nano-stainless steel material, which has excellent corrosion resistance and strength, can ensure the durability and safety of the tissue forceps, can be repeatedly sterilized and used, and can be widely used in the medical field.
