Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a pair of hand surgical curved forceps. Background Art

[0002] In addition to common skin lacerations, common injuries in hand surgery are often accompanied by tendon ruptures. Usually, a primary debridement and suture are performed after the injury. In order to ensure that the sutured tendon is firm, stable and can heal smoothly, the tendon planes need to be aligned during the suturing process. The existing surgical plan generally requires an assistant to align the tendon end planes. However, during the actual operation, the assistant and other factors may cause the tendon end plane to be lost, affecting the suture flatness, and thus affecting the suture tendon firmness and healing time.

[0003] The Chinese patent with patent number 202020014169.3 discloses a pair of surgical fixation forceps, which belongs to the field of medical devices, including a forceps rod one and a forceps rod two, one end of the forceps rod one is connected to the forceps handle, and the other end is hinged to the clamping rod, one end of the forceps rod two is connected to the forceps handle, and the other end is hinged to the forceps sleeve, the front parts of the forceps rod one and the forceps rod two are hinged together, the front end of the forceps sleeve is fixed with a clamping hook, the clamping rod is inserted into the forceps sleeve, the forceps rod one drives the clamping rod to move, the forceps rod two drives the forceps sleeve to move, the forceps sleeve drives the clamping hook to move, the clamping rod and the clamping hook cooperate to clamp broken bones or cracked bones; the surgical fixation forceps can conveniently clamp broken bones and cracked bones, which is convenient for orthopedic surgery. The fixation forceps can be used in combination. When clamping broken bones, the two broken bones can be clamped separately, which is convenient for subsequent surgery.

[0004] The above-mentioned existing technologies cannot solve the problem of achieving the tendon plane apposition function. Technical personnel in this field hope to propose a hand surgery curved forceps based on the existing technology, which can maintain and stabilize the plane of the tendon end without the assistance of an assistant, solve the problem of plane loss caused by manpower and other factors, thereby improving the firmness of tendon suture and accelerating the healing time.

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0020] Example 1

[0021] like Figure 1 As shown, a hand surgical curved forceps comprises a first forceps rod 1, a second forceps rod 2, a mating structure 3, and a locking structure 4. The first forceps rod 1 and the second forceps rod 2 are rotatably connected by a pin shaft.

[0022] The mating structure 3 includes a mating needle 301 and a connecting structure 302. The connecting structure 302 is provided at the ends of the first clamp rod 1 and the second clamp rod 2. The mating needle 301 is mounted on the connecting structure 302. The mating needle 301 is a syringe needle. The connecting structure 302 is an arc-shaped rod. One end of the arc-shaped rod is fixedly connected to the first clamp rod 1 and the second clamp rod 2, and the other end is sleeved with a syringe needle.

[0023] The connecting structure 302 is used to transmit the pinching force of the first clamp rod 1 and the second clamp rod 2 to the matching needle 301. In order to ensure that the direction of the force is consistent with the matching direction of the ruptured tendon, the arc rod can also be designed as a V-shaped rod or a U-shaped rod or other shapes.

[0024] During the operation, the two matching needles 301 are first set at the two ends of the broken tendon respectively, and then the connecting structure 302 of the matching structure 3 is inserted into the matching needle 301, and the clamping and kneading action of the first clamp rod 1 and the second clamp rod 2 drives the matching needle 301 to pull the two ends of the broken tendon close together and match in the same plane. The locking structure 4 locks the first clamp rod 1 and the second clamp rod 2 with each other, so that the two ends of the broken tendon are close to each other and remain in this position without deformation.

[0025] The locking structure 4 is provided at the other end of the first tongs rod 1 and the second tongs rod 2 and is used to lock the first tongs rod 1 and the second tongs rod 2 with each other.

[0026] The arc rod is connected and fixed to the first clamp rod 1 and the second clamp rod 2 at a certain angle, and the arc rods located at the ends of the first clamp rod 1 and the second clamp rod 2 have arc-shaped concave surfaces arranged opposite to each other.

[0027] By setting a transition between the arc-shaped rod and the first clamp rod 1 and the second clamp rod 2 and making a certain angle between the arc-shaped rod and the first clamp rod 1 and the second clamp rod 2, the moving direction of the engaging needle 301 can be changed when the first clamp rod 1 and the second clamp rod 2 are clamped and kneaded, so that the engaging needles 301 located at the ends of the first clamp rod 1 and the second clamp rod 2 can approach each other more smoothly.

[0028] The included angle between the arc rod and the first clamp rod 1 and the second clamp rod 2 is 10 degrees to 80 degrees.

[0029] By pre-designing a plurality of arc-shaped rods with different angles ranging from 10 degrees to 80 degrees, the utility model facilitates the quick selection of a more suitable one according to the distance between the two ends of the ruptured tendon during the operation.

[0030] The locking structure 4 includes a rack 401 arranged on the first clamp rod 1 and a ratchet 402 arranged on the second clamp rod 2. The rack 401 and the ratchet 402 are used in conjunction with each other. The ratchet 402 can move and lock on the rack 401. By adjusting the locking position of the rack 401 and the ratchet 402, the angle between the first clamp rod 1 and the second clamp rod 2 can be locked.

[0031] When the first clamp rod 1 and the second clamp rod 2 are clamped and kneaded, the ratchet 402 moves on the rack 401. When the two ends of the ruptured tendon are in contact with each other, the first clamp rod 1 and the second clamp rod 2 are released, and the locking structure 4 locks the angle between the first clamp rod 1 and the second clamp rod 2, so that the two ends of the ruptured tendon are kept in contact with each other, preparing for the suturing operation.

[0032] The matching needle 301 is configured as a plurality of syringe needles of different lengths and diameters, so that a more appropriate syringe needle size can be selected according to the different injuries of the patient.

[0033] Example 2

[0034] like Figure 1 As shown, as a preferred solution of embodiment 1, the ends of the first clamp rod 1 and the second clamp rod 2 away from the end of the engaging structure 3 are provided with clamp rod rings 5.

[0035] The clamp rod ring 5 is provided to prevent slipping and is more convenient to operate.

[0036] Example 3

[0037] As a preferred solution of Example 1, the arc rod is connected to the ends of the first clamp rod and the second clamp rod by fastening bolts. By fastening bolts, the connection angle between the arc rod and the first clamp rod and the second clamp rod can be arbitrarily changed and fastened, which makes it more convenient to use the arc rod with the matching needle head 301.

[0038] Finally, it should be noted that the embodiments described above are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
