Abstract
Description
Technical Field
[0001] This application relates to the field of bipolar electrocautery forceps technology, and in particular to a retractable tweezers structure for bipolar electrocautery forceps. Background Technology
[0002] Laparoscopic minimally invasive surgery requires the use of many laparoscopic surgical instruments, such as monopolar ablation electrodes, plasma electrosurgical units, or ultrasonic scalpels, to cut and separate target tissues or to stop bleeding. It also requires auxiliary instruments such as dissecting forceps, grasping forceps, suction devices, or bipolar electrocoagulation forceps.
[0003] The published patent, CN213525446U, describes a bipolar electrocoagulation forceps. This forceps includes a handle and a lever mounted on the handle. A branch tube is provided at the end of the lever near the forceps head; an end shell is installed at the end of the branch tube; and a camera module is disposed within the end shell. The beneficial effects of this invention are: when performing surgery on a patient, this bipolar electrocoagulation forceps can monitor the bleeding area in real time during hemostasis. The image of the bleeding area can be transmitted to an external display device, allowing the surgeon to intuitively obtain the real-time situation of the surgical area and avoid affecting the surgery due to blind spots. During the monitoring of the bleeding area, the monitoring position can be adjusted according to the actual surgical observation needs, thereby improving the monitoring range.
[0004] When the above devices are implemented, it is not convenient to retract the forceps head, which results in the forceps head being exposed to the outside for a long time. When not in use, it is easy for it to come into contact with other instruments used in the operation, which can easily cause contamination and affect the hygiene and safety of the operation. Utility Model Content
[0005] In view of the shortcomings of the prior art, this utility model provides a retractable tweezers structure for bipolar electrocoagulation forceps, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.
[0006] To achieve the above objectives, this application adopts the following technical solution: a retractable tweezers structure for bipolar electrocautery forceps, comprising a circular tube and elastic handles. Two elastic plates are symmetrically fixedly installed on the outer side of the circular tube, and the two elastic plates are inserted into the inner walls of the two elastic handles. A connecting seat is fixedly installed on the inner wall of the elastic handle. One side of a connecting arm is rotatably connected to the inner wall of the connecting seat, and a telescopic seat is rotatably connected to the other side of the connecting arm. A positioning tube is fixedly installed on the inner wall of the telescopic seat, and a movable tube is threaded onto the inner wall of the positioning tube. A first plier and a second plier are symmetrically fixedly installed on the inner wall of the movable tube.
[0007] In a preferred embodiment, the inner walls of both elastic handles are provided with insertion holes adapted to the shape of the elastic plates, and the two elastic plates are inserted into the inner walls of the two insertion holes.
[0008] By adopting the above technical solution, it is possible to easily connect the elastic plate and the elastic handle, and by moving the elastic handle, the elastic plate can slide on the inner wall of the socket, which can separate the round tube and the elastic handle.
[0009] In a preferred embodiment, there are two connecting seats and two connecting arms, which are symmetrically arranged on the inner sides of the two elastic handles. The two ends of the connecting arms are rotatably connected to the inner walls of the telescopic seat and the connecting seat, respectively.
[0010] By adopting the above technical solution, a stable supporting force can be provided for the telescopic seat, thereby ensuring that the telescopic seat and positioning tube will not shift when the elastic handle is pressed or released, thus ensuring stability.
[0011] In a preferred embodiment, the thickness of both jaw 1 and jaw 2 is 0.5mm, and the front ends of jaw 1 and jaw 2 are bent by a stamping machine and then fixedly connected with heat shrink tubing.
[0012] By adopting the above technical solution, when the two elastic handles are squeezed, the movable tube moves forward, and the first and second jaws can be closed and stored inside the inner wall of the movable tube, ensuring that they are not exposed. When the two elastic handles are released, the movable tube moves backward, and the first and second jaws can open.
[0013] In a preferred embodiment, the outer edges of the two elastic handles are provided with multiple anti-slip protrusions, the elastic handles are made of rubber, and the outer side of the elastic handles is arc-shaped.
[0014] By adopting the above technical solution, it is easier for medical staff to hold, and the friction when holding the hand is improved, so that it will not easily slip out of the hand.
[0015] In a preferred embodiment, the movable tube is provided with an external thread on the outer edge of the inner wall of the positioning tube, and the inner wall of the positioning tube is provided with an internal thread, and the internal thread and the external thread are threadedly connected.
[0016] By adopting the above technical solution, the positioning tubes can be stably connected to each other, ensuring that the positioning tubes can drive the movable tubes to move forward when the two elastic handles are squeezed.
[0017] The beneficial effects of this application are:
[0018] 1. This bipolar electrocoagulation forceps has a retractable forceps structure. By squeezing the two elastic handles, the connecting arm rotates on the inner wall of the connecting seat and the telescopic seat, which in turn pushes the movable tube forward through the positioning tube. At this time, the first and second jaws can be closed and stored in the inner wall of the movable tube. When the two elastic handles are released, the positioning tube will drive the movable tube to move backward, and then the first and second jaws can be opened. This solves the problem that when not in use, the forceps are easy to come into contact with other instruments used in the operation, which can easily cause contamination.
[0019] 2. The retractable tweezers structure of this bipolar electrocoagulation forceps allows two elastic plates to move and detach from the inner walls of the two elastic handles by pulling the round tube backward, thereby achieving separation between the elastic plates and the elastic handles. The positioning tube and the movable tube are connected by threads, and separation can be achieved by rotation, which facilitates the disassembly and individual replacement of parts.

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0026] Reference Figure 1-4 A retractable tweezers structure for bipolar electrocautery forceps includes a round tube 1 and elastic handles 3. Two elastic plates 2 are symmetrically fixedly installed on the outer side of the round tube 1, and the two elastic plates 2 are inserted into the inner walls of the two elastic handles 3. A connecting seat 5 is fixedly installed on the inner wall of the elastic handle 3. One side of the connecting arm 6 is rotatably connected to the inner wall of the connecting seat 5, and a telescopic seat 7 is rotatably connected to the other side of the connecting arm 6. A positioning tube 8 is fixedly installed on the inner wall of the telescopic seat 7. A movable tube 9 is threadedly installed on the inner wall of the positioning tube 8. Pliers claw one 10 and pliers claw two 11 are symmetrically fixedly installed on the inner wall of the movable tube 9.
[0027] See Figure 4 The inner walls of the two elastic handles 3 are provided with insertion holes 4 that are adapted to the shape of the elastic plate 2. The two elastic plates 2 are inserted into the inner walls of the two insertion holes 4, so that the elastic plate 2 and the elastic handle 3 can be easily connected. Moving the elastic handle 3 causes the elastic plate 2 to slide on the inner wall of the insertion hole 4, which can separate the round tube 1 and the elastic handle 3.
[0028] See Figure 4 There are two connecting seats 5 and two connecting arms 6, and the two connecting seats 5 and two connecting arms 6 are symmetrically arranged on the inner side of the two elastic handles 3. The two ends of the connecting arms 6 are rotatably connected to the inner wall of the telescopic seat 7 and the connecting seat 5, respectively, so as to provide stable support for the telescopic seat 7, thereby ensuring that the telescopic seat 7 and the positioning tube 8 will not be positioned when the elastic handle 3 is pressed or released, thus ensuring stability.
[0029] See Figure 1 The thickness of both jaw 10 and jaw 21 is 0.5mm. The front ends of jaw 10 and jaw 211 are bent by a stamping machine and then fixed with heat shrink tubing. When the two elastic handles 3 are squeezed, the movable tube 9 moves forward and jaw 10 and jaw 21 can be closed and stored in the inner wall of the movable tube 9 to ensure that they are not exposed. When the two elastic handles 3 are released, the movable tube 9 moves backward and jaw 10 and jaw 21 can be opened.
[0030] See Figure 1 - Figure 4 The outer edges of the two elastic handles 3 are provided with multiple anti-slip protrusions. The elastic handles 3 are made of rubber and the outer side of the elastic handles 3 is arc-shaped, which makes it easy for medical staff to hold and increases the friction when holding the hand, so that it will not easily slip out of the hand.
[0031] See Figure 3 and Figure 4 The movable tube 9 is provided with an external thread on the outer edge of the inner wall of the positioning tube 8, and the inner wall of the positioning tube 8 is provided with an internal thread. The internal thread and the external thread are connected by a thread, which can securely connect the positioning tube 8 to the positioning tube 8, ensuring that the positioning tube 8 can drive the movable tube 9 to move forward when the two elastic handles 3 are squeezed.
[0032] Working principle: When using this device, by squeezing the two elastic handles 3, the connecting arm 6 rotates on the inner wall of the connecting seat 5 and the telescopic seat 7, which in turn pushes the movable tube 9 forward through the positioning tube 8. At this time, the first jaw 10 and the second jaw 11 can close and be stored in the inner wall of the movable tube 9, ensuring that it is not exposed. When the two elastic handles 3 are released, the positioning tube 8 will drive the movable tube 9 to move backward, and then the first jaw 10 and the second jaw 11 can open. By pulling the round tube 1 backward, the two elastic plates 2 can be moved and separated from the inner wall of the two elastic handles 3, thereby realizing the separation between the elastic plates 2 and the elastic handles 3. The positioning tube 8 and the movable tube 9 are connected by threads, and rotation can realize separation, which facilitates the disassembly and individual replacement of parts.
