Description

Technical Field

[0001] The utility model relates to the field of surgical instruments, in particular to a needle holding forceps used for surgical suturing. Background Art

[0002] In traditional surgical suturing, the surgeon needs to constantly use needle holders and scissors to suturing and cutting, which causes the suturing operation to take more time and affects work efficiency. In addition, during deep tissue suturing, the scissors need to enter the deep tissue suturing position. If you are not careful, the tip and blade of the scissors can easily scratch the deep tissue, causing secondary damage to the patient.

[0003] The utility model patent "Needle Holder" with publication number CN220109780U has a shearing section at the tail end of the beak of the needle holder. During deep tissue suturing, when the shearing section is used to cut the suture thread, the beak of the needle holder needs to be fully opened so that the shearing section at the tail end of the beak of the needle holder can be used to cut the suture thread. Therefore, the beak of the needle holder has a large opening angle, which can easily cause secondary trauma to the patient's deep tissue. At the same time, the surgeon's hand holding the needle holder is required to be opened to a large extent, which can easily cause hand fatigue of the surgeon, resulting in the needle falling off or even the needle holder falling off, thereby causing greater trauma to the patient.

[0004] At present, a surgical needle holding forceps has a razor blade tied to a handle (see Figure 7 ), which is mainly used for sutures and cuttings on the skin surface. Since the needle holder uses a razor blade to cut the suture, the suture needs to be straightened before the cutting operation can be performed, and the straightened suture is easy to cause harm to the patient. In addition, since the razor blade tied to the needle holder is exposed to the outside, it is easy to fall off during the needle holding and suturing process, which is easy to cause harm to the patient and medical staff. It is not suitable for sutures and cuttings in deep tissues. Summary of the invention

[0005] The utility model aims to provide a needle holding forceps for surgical suturing in view of the deficiencies in the prior art, which has the advantages of convenient operation, high working efficiency and wide application range.

[0006] A needle holding forceps for surgical suturing comprises left and right forceps bodies having forceps beaks and forceps handles, the left and right forceps bodies are hinged to form a needle holding forceps that can be opened or closed, the facing surfaces of the forceps beaks of the left and right forceps bodies are respectively provided with open through grooves, the notches of the two open through grooves face each other, the open through grooves are 6 to 8 mm away from the front end of the forceps beak, and this distance is the clamping surface of the forceps beak, and blades for cutting sutures are respectively installed in each open through groove, the cutting edges of the blades face each other and extend longitudinally along the forceps beak, wherein the cutting edge of at least one blade protrudes from the clamping surface of the forceps beak, so that the two blades form a pair of scissors for cutting sutures, constituting a needle holding forceps with sutures and scissors integrated.

[0007] Preferably, the open through grooves provided on the jaws of the left and right pliers bodies are both step grooves, and the blades are fixedly mounted on the step portions of the step grooves by means of screws.

[0008] Preferably, the height of the cutting edge of the blade protruding from the clamping surface of the beak of the forceps is 1 mm.

[0009] Preferably, the blade edge portion of the blade protruding from the clamping surface of the pliers beak is set as a bevel blade, the lower end of the bevel blade is adjacent to and flush with the clamping surface, and the high end of the bevel blade protrudes from the clamping surface of the pliers beak by a height of 1 mm.

[0010] Preferably, the slot width of the open through slot is 5 mm, and the length of the blade is the same as the slot width.

[0011] Preferably, the clamping surface is made of magnetic material, and the clamping surface is bonded to the beak of the forceps.

[0012] Preferably, the cross section of the open through groove is rectangular or semicircular.

[0013] Beneficial effects of the utility model:

[0014] When the needle holder of the utility model is used to hold a suture needle, after completing the suturing operation, it is only necessary to move the suture back about 5 mm to use the blade to cut the surgical suture. Therefore, the opening angle of the needle holder is very small. During the suturing and cutting operation of the deep tissue of the wound, the operation is convenient, and no secondary damage will be caused to the deep tissue of the patient's wound. It can also reduce the hand fatigue of the surgeon. Moreover, the utility model can quickly complete the suturing and cutting process by a single person without the assistance of an assistant, especially when facing multiple or batches of wounded patients who need debridement and suturing, the suturing and cutting process can be quickly completed, which can shorten the operation time and improve work efficiency. In addition, the blade of the utility model is fixed to the step portion of the step groove by a screw, which is convenient for removing the blade, and after removing the blade, the needle holder can be fully disinfected and sterilized.

[0022] See also Figures 1 to 6 A needle holding forceps for surgical suturing comprises a left and right forceps body having a forceps beak and a forceps handle, wherein the left and right forceps body are hinged by rivets to form a needle holding forceps that can be opened or closed, and the facing surfaces of the forceps beaks 2 of the left and right forceps body are respectively provided with open slots 3, the notches of the two open slots 3 face each other, and the cross section of the open slots 3 is rectangular or semicircular. In this embodiment, the cross section of the open slots 3 is rectangular. The notch width of the open slots 3 is 5mm, and the distance between the open slots 3 and the front end of the forceps beak 2 is 6 to 8mm, which is the clamping surface 21 of the forceps beak 2. The forceps beak of the needle holding forceps is about 2cm, and generally 1 / 3 of the front end of the forceps beak is used to clamp the suture needle. The clamping surface 21 is made of magnetic material, and the clamping surface 21 is bonded to the forceps beak 2. The clamping surface 21 is magnetic, and the suture needle is more stable when clamping and is not easy to fall off. The open through grooves 3 are all step grooves, and the blade 1 for cutting sutures is fixedly installed on the step portion 31 of the step groove by screws in each open through groove 3. The advantage of fixing the blade by screws is that when the blade is blunt or damaged, it is convenient to replace the blade; or when the needle holder is used, the blade can be removed when the needle holder is disinfected, so that there is no dead angle for disinfection; or the blade is a disposable item, and it is convenient to remove and discard the blade after each use. In addition, the blade is close to the needle holder. When cutting the thread, the surgeon only needs to open the handle of the clamp slightly (that is, the angle of the beak of the needle holder is small) to move the surgical suture to the blade to cut the thread, which can avoid hand fatigue caused by the surgeon's large hand opening, and can avoid secondary damage to the patient when suturing deep tissue. The length of the blade is the same as the slot width, which is 5mm. For medical surgical sutures with a diameter of less than 0.4mm, the length of the 5mm blade is fully capable of cutting the surgical suture. The cutting edges 11 of the blades 1 face each other and extend longitudinally along the beak 2, wherein the cutting edge 11 of at least one blade protrudes from the clamping surface 21 of the beak 2, and the cutting edge 11 is a beveled blade, the lower end of the beveled blade is adjacent to and flush with the clamping surface 21, and the high end of the beveled blade protrudes from the clamping surface 21 of the beak 2 by a height of 1 mm. In this embodiment, the cutting edge of the blade installed on the left body of the needle holding forceps is a beveled blade, and the cutting edge of the blade installed on the right body is flush with the clamping surface 21. The setting of the beveled blade is to facilitate the surgeon to move the surgical suture to the blade position, and the cutting edge of the blade protrudes from the clamping surface 21 of the beak 2 to ensure that the two blades 1 can form a scissors structure for cutting the suture.

[0023] The operation method of the needle holding forceps used for surgical suturing is as follows: the surgeon holds the handle of the needle holding forceps of the utility model with one hand, and uses the clamping surface 21 at the front end of the forceps beak 2 of the needle holding forceps to clamp the suture needle for suturing operation. When it is necessary to cut the thread, the surgeon clamps the suture needle with tweezers, then slightly opens the needle holding forceps, and then moves the suture thread backward by about 5 mm so that the suture thread contacts the blade of the blade, and then closes the forceps beak to cut the suture thread to complete the thread cutting operation.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification made to the present invention by those skilled in the art without departing from the spirit of the present invention shall fall within the protection scope of the present invention.
