Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an S-shaped surgical forceps. Background Art

[0002] Surgery is a way to treat diseases, and it uses a technical means to achieve the purpose of removing diseases. Although there are differences in the size and difficulty of surgeries, there is no clear scope and precise definition. There are many types of surgeries in clinical practice, such as incision, drainage, removal, anastomosis, repair, transplantation, etc. Some surgeries also require the sincere cooperation of related departments to complete. The surgeon can complete them independently or work closely with assistants to complete them together. During the operation, surgical forceps are one of the more commonly used medical instruments.

[0003] The patent with announcement number CN218009861U discloses a surgical forceps, which includes a left forceps arm, a right forceps arm, a left forceps body arranged at one end of the left forceps arm, a right forceps body arranged at one end of the right forceps arm, a left finger ring arranged at the other end of the left forceps arm, and a right finger ring arranged at the other end of the right forceps arm, wherein the left forceps arm is hinged with the right forceps arm; the left forceps body is a semi-ellipsoidal shell, the right forceps body is a semi-ellipsoidal shell, the left forceps body and the right forceps body cooperate to form an ellipsoidal shell, the front ends of the left forceps body and the right forceps body are provided with mutually matching engaging teeth, the device designs the forceps body into a semi-ellipsoidal shell, will not damage the wall of the natural cavity when entering and exiting the natural cavity, and can easily remove the tissue to be removed through the natural cavity, while effectively avoiding damage to the tissue, is simple to operate, and is easy to use. The invention is convenient and has good practicality, and is particularly suitable for the current clinical surgery of taking specimens through natural cavity. However, the device has the problem that a bending part is set between the connecting arm and the support arm so that the hand-held part on the end of the support arm is bent and tilted, so as to operate on the side position of the armpit during the surgery. However, the tilt angle of the bending part is fixed, and the side position of the armpit during minimally invasive cardiac surgery of different patients is different. If such surgical forceps with multiple tilt angle bending parts are made to meet the conditions of various patients, not only the use cost is increased, but also the surgical forceps need to be selected and replaced according to the specific conditions during the surgery, which is very troublesome. For this reason, an S-shaped surgical forceps is proposed to solve the problem that it is difficult for the existing surgical forceps to freely adjust the tilt angle of the forceps head according to the needs.

Inside, the fixed rotating shaft 603 is fixedly connected with the arc-shaped fixed seat 602 but can rotate in the adjusting groove 601, the inner wall of the adjusting groove 601 is provided with a movable groove 605, the inner cavity of the movable groove 605 is provided with a movable plate 606, one side of the movable plate 606 is fixedly connected with a clamping block 608, the top and bottom of the clamping block 608 are provided with guide slopes 609, the arc-shaped surface of the arc-shaped fixed seat 602 is provided with a plurality of rectangular teeth 604, the inner cavity of the movable groove 605 is fixedly connected with a spring 607, the spring 607 is fixedly connected with the movable plate 606, the top of the upper clamp arm 1 and the lower clamp arm 2 are penetrated by a limit pin 610, and the limit pin 610 penetrates the inner cavity from the adjusting arm 5 to the movable plate 606.

[0021] Furthermore, the two adjustment arms 5 are longitudinally parallel to each other and are arranged in parallel to ensure that when the adjustment arms 5 are connected using the limit buckle 7, the upper clamp arm 1 and the lower clamp arm 2 can be rotated to simultaneously adjust the angles between the two clamp walls and the two adjustment arms 5.

[0022] Furthermore, an arc groove 8 is provided at the relative position in the middle of the upper forceps arm 1 and the lower forceps arm 2, and an anti-skid pad 9 is provided in the inner cavity of the arc groove 8. The upper forceps arm 1, the lower forceps arm 2, the adjustment arm 5 and the arc groove 8 form an approximately S-shaped surgical forceps structure, which, together with the anti-skid pad 9 in the arc groove 8, can clamp larger medical supplies and tools during surgery, thereby improving the functionality of this S-shaped surgical forceps.

[0023] Furthermore, the mating surfaces of the two pliers heads 4 are provided with anti-slip teeth 10 , and the anti-slip teeth 10 are used to increase the friction force of the pliers heads 4 when clamping.

[0024] Working principle: When using this S-shaped surgical forceps, according to the clamping requirements of the surgical site, the adjustment mechanism 6 between the upper forceps arm 1, the lower forceps arm 2 and the adjustment arm 5 can be used to adjust the angle between the two free forceps walls and the adjustment arm 5. After removing the limit buckles 7 on the two adjustment arms 5, the fingers can be passed through the rings on the adjustment arms 5, and the surgery can be performed with the fixing pins 3 and the forceps head 4, which improves the applicability of this S-shaped surgical forceps and solves the problem that the existing surgical forceps are difficult to freely adjust the tilt angle of the forceps head according to the requirements; when adjusting the angle between the adjustment arm 5 and the two forceps arms, the limit pin 610 is pulled out, and the two forceps are held. The adjusting arm 5 rotates the upper clamp arm 1 and the lower clamp arm 2, and cooperates with the arc-shaped fixed seat 602 and the fixed rotating shaft 603 in the adjusting groove 601, and the clamp arm rotates. During the process, under the action of the guide slope 609, the clamp block 608 flips over the rectangular teeth 604, and the movable plate 606 in the movable groove 605 is compressed inward. After reaching the appropriate position, it cooperates with the spring 607, and the clamp block 608 automatically enters between the rectangular teeth 604, and the limit pin 610 is reinserted to fix the angle between the upper clamp arm 1, the lower clamp arm 2 and the adjusting arm 5, thereby achieving the purpose of self-adjustment of the bending degree of this S-shaped surgical forceps and improving applicability.
