Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a biopsy forceps for positioning orthopedic surgical robots. Background Technology

[0002] Orthopedic surgery is a surgical treatment for patients with orthopedic and related conditions. In orthopedic surgery, surgical robots are usually used to locate the surgical site. For cancer patients, tissue samples are taken using biopsy forceps for later analysis.

[0003] In existing technologies, biopsy forceps are generally used to extract cells and lesions from bone tissue by gripping and pulling them with a pair of cutting plates at the bottom. However, when using biopsy forceps, the gripping and pulling of the cutting plates may damage healthy tissue, and the pedicle of the tissue being gripped may not be cut off in time, resulting in the tissue not being properly removed and affecting sampling efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a biopsy forceps specifically designed for positioning in orthopedic surgical robots, in order to solve the problem that existing biopsy forceps, when in use, can only make a circular cut in the tissue by rotating the cutting plate, without cutting off the pedicle, so the tissue cannot be well removed, thus affecting the sampling efficiency.

[0005] To achieve the above objectives, a biopsy forceps for positioning in orthopedic surgical robots is provided, including a positioning forceps. A positioning plate is installed on one side of the positioning forceps. A threaded hole is opened in the middle of the positioning plate. A rotating shaft is threadedly connected to the threaded hole. A sliding column is slidably arranged inside the rotating shaft. A fixing box is fixed to the bottom end of the rotating shaft. The end of the sliding column away from the positioning plate is located inside the fixing box. A pair of cutting plates for cutting pathological tissue are arranged on the side of the fixing box away from the positioning plate. A sliding component for moving the pair of cutting plates is arranged on the end of the sliding column away from the positioning plate and inside the fixing box.

[0006] As a further improvement to this technical solution, the sliding assembly includes a fixing rod fixedly connected to two mutually perpendicular inner walls of the fixed box, a sleeve slidably connected to the outside of the fixing rod, a cutting plate fixedly connected to the outside of the sleeve, and a connecting rod fixedly connected between the sleeve and the sliding column.

[0007] As a further improvement to this technical solution, a through hole is provided inside the rotating shaft to communicate with the fixed box, and the sliding column slides inside the through hole.

[0008] As a further improvement to this technical solution, a camera is fixedly connected to the end of the sliding column located inside the fixed box.

[0009] As a further improvement to this technical solution, a positioning pin is fixedly connected to one side of the positioning clamp, and a connecting block is rotatably connected to the outside of the positioning pin. The connecting block has a connecting pin fixedly connected to one end near the positioning plate, and the positioning plate is hinged to the outside of the connecting pin.

[0010] As a further improvement to this technical solution, a compression spring is fixedly connected between the two clamp arms of the positioning clamp, and a telescopic rod is provided inside the compression spring to limit the compression spring.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This orthopedic surgical robot features a dedicated biopsy forceps with a sliding component. The sliding column moves up and down inside the rotating shaft, allowing a pair of cutting plates to grip and release pathological tissue. The rotating shaft is threaded to the center of the positioning plate, so the rotation of the shaft drives a pair of opposing inclined cutting plates. This moves the gripped pathological tissue outward while simultaneously cutting off the pedicle at the bottom of the tissue, greatly improving sampling efficiency and avoiding damage to healthy tissue caused by gripping and pulling. Through the coordinated use of the positioning column, connecting block, and connecting column, the device can collect pathological tissue from different positions, improving the overall practicality of the device.

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0020] Please see Figures 1-3 As shown, this utility model embodiment provides a special biopsy forceps for positioning in orthopedic surgical robots. The orthopedic biopsy forceps includes the following components:

[0021] Specifically, it includes a positioning clamp 1, a positioning plate 2 installed on one side of the positioning clamp 1, a threaded hole 3 in the middle of the positioning plate 2, a rotating shaft 4 internally threaded through the threaded hole 3, a sliding column 5 slidably disposed inside the rotating shaft 4, a fixed box 6 fixedly connected to the bottom end of the rotating shaft 4, the end of the sliding column 5 away from the positioning plate 2 located inside the fixed box 6, a pair of cutting plates 7 for cutting pathological tissues disposed on the side of the fixed box 6 away from the positioning plate 2, a sliding assembly for moving the pair of cutting plates 7 disposed on the end of the sliding column 5 away from the positioning plate 2 and inside the fixed box 6, the sliding assembly including a fixing rod 8 fixedly disposed on two mutually perpendicular inner walls of the fixed box 6, a sleeve 9 slidably connected to the outside of the fixing rod 8, the cutting plate 7 fixedly disposed on the outside of the sleeve 9, a connecting rod 10 fixedly disposed between the sleeve 9 and the sliding column 5, a through hole 11 communicating with the fixed box 6 disposed inside the rotating shaft 4, and the sliding column 5 sliding inside the through hole 11.

[0022] The above technical solution involves pushing the sliding column 5 into the through hole 11 inside the rotating shaft 4, causing the connecting rod 10 at one end of the sliding column 5 to simultaneously drive the sleeve 9 to move downward from the highest point of the fixing rod 8 on the two perpendicular inner walls of the fixing box 6. At this time, a pair of opposing inclined cutting plates 7 fixed to the outside of the sleeve 9 clamp the pathological tissue. Then, the rotating shaft 4 is rotated into the threaded hole 3 in the middle of the positioning plate 2, causing the pair of cutting plates 7 to rotate and cut off the stalk at the bottom of the clamped pathological tissue. At the same time, the rotation of the rotating shaft 4 will also drive the clamped pathological tissue to move outward, which greatly improves the sampling efficiency and avoids damage to healthy tissue caused by clamping and pulling.

[0023] Specifically, the end of the sliding column 5 located inside the fixed box 6 is fixed with a camera 12.

[0024] The above technical solution uses camera 12 to monitor the location of pathological tissue in real time, ensuring accuracy.

[0025] Specifically, a positioning pin 13 is fixedly connected to one side of the positioning clamp 1, and a connecting block 14 is rotatably connected to the outside of the positioning pin 13. A connecting pin 15 is fixedly connected to one end of the connecting block 14 near the positioning plate 2. The positioning plate 2 is hinged to the outside of the connecting pin 15. A compression spring 16 is fixedly connected between the two clamp arms of the positioning clamp 1. A telescopic rod 17 is provided inside the compression spring 16 to limit the compression spring 16.

[0026] The above technical solution, with the connecting block 14 rotatably connected to the positioning column 13 and the positioning plate 2 hinged to the connecting block 14, allows the equipment to be adjusted horizontally and vertically, enabling the collection of pathological tissues from different locations and improving the overall practicality of the equipment.

[0027] Working principle: Before operation, the positioning clamp 1 is installed on the robotic arm. The clamp 1 is positioned next to the pathological site on the limb to prevent the patient from moving due to pain, which could affect the collection quality and efficiency. The location of the pathological tissue to be collected is then observed through the camera 12. The rotating shaft 4 is then twisted towards the pathological tissue, causing the screw thread of the shaft 4 to rotate in the middle of the positioning plate 2. This moves a pair of opposing inclined cutting plates 7 to the designated position. At this point, the sliding column 5 is pushed towards the pathological tissue and slides into the through hole 11 inside the rotating shaft 4. Simultaneously, the connecting rod 10 at one end of the sliding column 5 drives the sleeve 9 to move downwards from the highest point of the fixed rods 8 on the two perpendicular inner walls of the fixed box 6. At this time, the pair of opposing inclined cutting plates... 7. As the sleeves 9 slide downwards on the outside of the fixed rod 8, they move closer to each other until the pathological tissue is clamped. Then, the rotating shaft 4 is rotated in the opposite direction, causing the pair of cutting plates 7 to rotate and remove the stalk at the bottom of the clamped pathological tissue. At the same time, the rotation of the rotating shaft 4 will also drive the clamped pathological tissue to move outward, thereby realizing tissue sampling of tumor patients. When the device needs to sample pathological sites at different locations, the positioning plate 2 is picked up and the connecting block 14 is rotated on the positioning column 13, which can realize the vertical and horizontal rotation of the device on the positioning plate 2. The positioning plate 2 is hinged to the connecting block 14, which allows the device to be adjusted horizontally to collect pathological tissue at different locations, improving the overall practicality of the device.
