Description

Gynecological tumor operation is with snatching pincers

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to gynaecology's tumour operation is with snatching pincers.

Background

When the gynecological tumor operation is performed, a grabbing clamp is usually needed. With the increasing demand of patients for surgery, many patients want the incision for surgery to be as small as possible, especially women's nature to love beauty, and do not want to leave long scars on their bodies. However, the current grasping forceps commonly used in gynecological surgery are similar to scissors in structure, and the opening and closing degree of forceps heads is generally controlled through crossed forceps handles. When a doctor carries out clamping operation in a linear mode, the clamp head can directly clamp human tissues near an incision; however, when a surgeon needs to grasp the tissue on the side of the incision, the surgeon needs to press the incision with the forceps body to force the incision edge to be spread extremely, so that the jaws can grasp the body tissue on the side of the incision at an inclined angle. This is caused by the structure of the current grasping forceps themselves, which is contrary to the small incision desired by the patient. Therefore, there is a need for an improved grasping forceps.

Detailed Description

The invention will be further explained with reference to the following figures and examples:

as shown in fig. 1, fig. 2 and fig. 3, the utility model discloses a grasping forceps for gynecological tumor operation, which comprises two forceps rods with the same structure. For convenience of description, the two clamp rods are called a left clamp rod and a right clamp rod in the scheme.

The forceps rod comprises a forceps head bending section 21 and a forceps handle straight section 22. The end of the straight section 22 of the forceps handle far away from the bending section 21 of the forceps head is integrally formed with a finger ring part 23, and the finger ring part 23 can be inserted by the fingers of a doctor to operate the forceps rod. In addition, in order to facilitate the taking operation of the doctor, an anti-skid silica gel sleeve is further sleeved on the surface of the ring part 23.

The left forceps rod and the right forceps rod are hinged together through a pin shaft 4 to form a structure similar to a pair of scissors, and the two forceps head bending sections 21 can be opened and closed by operating the two forceps handle straight-line sections 22. As shown in fig. 1, the head bending sections 21 of the left and right forceps rods each extend in a bent manner in one direction. That is, when an object needs to be gripped, the two bending sections 21 are in one direction, whether they are opened or closed. The structure is designed so that when the arms of a doctor are in the direction vertical to the incision, the two bending sections 21 of the forceps head can clamp human tissues to the side parts in the vertical direction.

The structure realizes the clamping of the human tissue at the incision part, but the human tissue is not easy to position due to non-conventional operation. In this scheme, universal clamping components are arranged at the end parts of the bending sections 21 of the binding clip of the left binding clip and the right binding clip, which are far away from the straight line section 22 of the binding clip handle. As shown in fig. 3, the universal clamping assembly includes a pressing head 13, a semicircular retaining ring 11 and a connecting shaft 12, the pressing head 13 is rotatably connected with the bending section 21 of the binding clip through the connecting shaft 12, the axial direction of the connecting shaft 12 is perpendicular to the opening and closing plane of the two binding clip, the semicircular retaining ring 11 is coaxially arranged with the connecting shaft 12, the semicircular retaining ring 11 is fixedly connected to the bending section 21 of the binding clip, and the rotation limit included angle value of the pressing head 13 along the connecting shaft 12 is limited by the semicircular retaining ring 11.

In order to firmly connect the pressing head 13 with the human tissue, the side of the pressing head 13 away from the connecting shaft 12 is integrally formed with a corrugated tooth 13 a. In the specific implementation: the surgeon operates the left and right clamp bars in a direction perpendicular to the incision. But only the two bent sections 21 of the binding clip and the two universal clamping assemblies of the left and right clamping bars extend into the incision. The rotation angle of the pressure head 13 is limited by the semicircular retaining ring 11, so that the pressure head 13 can be basically at a controllable angle when being close to human tissue. The doctor operates the left forceps rod and the right forceps rod to enable the two pressing heads 13 to gradually fold towards the human tissue, and in the process, the two pressing heads 13 realize self angle adjustment and finally clamp the human tissue.

In the process, the doctor does not need to press the incision and incline the left forceps rod and the right forceps rod to clamp the human tissues at the side part of the incision, so that the requirement on the size of the incision is not large, the operation can be finally completed under a small incision, the patient's desire is met, and the postoperative scar is minimized.

When a doctor clamps, if the left forceps rod and the right forceps rod need to be forced to be closed all the time, the operation is inconvenient. For this purpose, we also design the self-locking mechanism 3. The automatic locking mechanism 3 not only can meet the opening and closing requirements of the left clamp rod and the right clamp rod, but also can automatically lock the opening and closing angles of the left clamp rod and the right clamp rod.

The automatic locking mechanism 3 comprises a locking rod 32, a one-way bearing 33, a gear 31 and a tension spring 34, the locking rod 32 is integrally arc-shaped, the locking rod 32 is rotatably connected with the left clamp rod, one end of the tension spring 34 is fixed to the middle of the locking rod 32, and the other end of the tension spring 34 is fixed to the left clamp rod. The gear 31 and the one-way bearing 33 are coaxially arranged, and the gear 31 is rotatably connected with the right nipper rod through the one-way bearing 33. Sawtooth is arranged on the inner arc surface of the locking rod 32, the inner arc surface of the locking rod 32 is pressed towards the gear 31 under the action of the tension spring 34, and the sawtooth is meshed with the gear 31. That is, the gear 31 is rotated in one direction to move the locking lever 32 only in the direction in which the left and right clamp levers are closed relatively.

In operation, if the left and right clamp levers are opened or opened, the physician needs to pull the locking lever 32 with another hand in a direction close to the finger ring portion 23 to disengage the locking lever 32 from the gear 31, and the left and right clamp levers can be opened or closed arbitrarily. When the doctor releases the locking lever 32 by hand, the inner arc surface of the locking lever 32 is meshed with the gear 31 under the action of the tension spring 34. But the gear 31 can only rotate in one direction due to the one-way bearing 33. Therefore, the left and right clamp rods can only be closed continuously, and the universal clamping assembly is promoted to clamp human tissues continuously. And at this time, as long as the universal clamping assembly clamps the human tissue, even if the doctor releases the left clamp rod and the right clamp rod by hand, the universal clamping assembly can still clamp the human tissue and cannot be loosened. So as to facilitate the operation of the doctor.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
