Description

Technical Field

[0001] This utility model relates to the field of surgical instruments, and in particular to a novel endoscopic working cannula suitable for the reduction of fracture fragments within the spinal canal. Background Technology

[0002] For burst fractures of the thoracolumbar vertebrae with fracture fragments occupying space within the spinal canal, traditional open surgery is highly invasive, and minimally invasive treatment using spinal endoscopy has become a trend.

[0003] However, existing endoscopic working cannulas are designed for degenerative diseases, and their use for rotational manipulation and reduction of fracture fragments within the cannula presents numerous inconveniences. These include a fixed angle at the cannula's tip, limited maneuvering range due to stenosis of the tip, and slippage upon contact with the bone fragment due to the smooth tip. Therefore, there is an urgent clinical need for a novel endoscopic working cannula suitable for reducing fracture fragments within the spinal canal, but current technology lacks corresponding equipment. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a novel endoscopic working cannula with an adjustable tilting part that can be adjusted during minimally invasive surgery to move and reposition fracture fragments. This cannula is suitable for repositioning fracture fragments within the spinal canal.

[0005] The equipment includes a sleeve body, which is the assembly base of the equipment;

[0006] A tilting part is hinged to the front of the sleeve body, and a tilting connecting rod is hinged to the bottom of the tilting part. The tilting connecting rod extends out of the tail end of the sleeve body.

[0007] The effect achieved in this way is that, during the operation, the lifting linkage moves the lifting part, causing it to perform pitch angle adjustment, thereby adapting to the lifting action of the fracture fragment. In other words, on the one hand, the lifting part is hinged, and by pushing forward or pulling back the lifting linkage, the pitch of the lifting part can be adjusted to adapt to the position of the fracture fragment; and based on the above adjustment, rotating the cannula body can perform a longer downward or upward lifting action on the fracture fragment, so that the fracture fragment is reduced in the above manner.

[0008] The beneficial effects of this utility model are: This utility model fills a gap in the market with a simple structure, realizing the use of the endoscopic working sleeve for the rotation and prying repositioning of fracture fragments inside the tube; in particular, the prying part at the front of the device can be adjusted for pitch, and the outside is provided with an anti-slip surface; it can adapt to the angle of the fracture fragments and play an anti-slip role during the prying process.

[0015] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0016] Reference Figure 1 , Figure 2 The present invention provides a novel endoscopic working sleeve suitable for repositioning fracture fragments within the spinal canal, comprising a sleeve body 1, which serves as the assembly basis for the device.

[0017] A tilting part 2 is hinged to the front of the sleeve body 1, and a tilting connecting rod 4 is hinged to the bottom of the tilting part 2. The tilting connecting rod 4 extends out of the tail end of the sleeve body 1.

[0018] During use, in the surgical procedure, the lifting linkage 4 drives the lifting part 2 to perform pitch angle adjustment, thereby adapting to the lifting action of the fracture fragment. In other words, the lifting part 2 is hinged, and by pushing forward or pulling back the lifting linkage 4, the pitch of the lifting part 2 can be adjusted to adapt to the position of the fracture fragment. Based on the above adjustment, rotating the sleeve body 1 can perform a longer downward or upward lifting action on the fracture fragment, so that the fracture fragment is reduced in the above manner.

[0019] Example 1, refer to the accompanying drawings in the specification. Figure 1 or Figure 3 The aforementioned tilting part 2 is in the form of a curved plate with an arc-shaped front end; its width is not greater than the outer diameter of the sleeve body 1.

[0020] This ensures that the equipment can perform the puncture procedure normally.

[0021] In Example 2, the front of the sleeve body 1 and the rear of the tilting part 2 are integrally connected with ear plates; the sleeve body 1 and the tilting part 2 are hinged together by the ear plates.

[0022] The effect achieved is that the tilting part 2 can be adjusted to a wider pitch angle.

[0023] In Example 3, the outer surface of the raised part 2 is integrally provided with an anti-slip surface.

[0024] Preferably, the anti-slip surface is processed by any one of sandblasting, titanium spraying, or anti-slip texture.

[0025] The effect achieved is to prevent the equipment from slipping during the prying process.

[0026] Example 4, refer to the accompanying drawings in the specification. Figure 4 The sleeve body 1 is provided with an endoscope channel 6 and a lever connecting rod channel 5.

[0027] Preferably, the inner diameter of the endoscope channel 6 is larger than the inner diameter of the lever channel 5.

[0028] This achieves the effect of avoiding interference between the endoscope and the lifting linkage 4, thus ensuring the surgical field of vision.

[0029] Furthermore, the bottom surface of the tilting link 4 is provided with an inclined ear plate, and the tilting link 4 passes through the tilting link channel 5 and is hinged to the ear plate.

[0030] The rear part of the lever connecting rod channel 5 is provided with an assembly base plate, and the assembly base plate is provided with screw holes.

[0031] The lever connecting rod 4 includes a connecting rod part and a screw part. The screw part is rotatably disposed at the tail end of the connecting rod part and screwed into the screw hole of the mounting base plate.

[0032] The effect achieved is that the forward or backward movement of the lever 4 can be controlled by rotating the screw, thereby achieving mechanical self-locking.

[0033] Furthermore, a hexagonal rotating part is integrally provided behind the screw section.

[0034] This makes it easier to twist.

[0035] Furthermore, the connecting rod and the screw are rotatably connected by bearings or male and female joints.

[0036] In Example 5, a flipping link 3 is also provided on the outside of the rear part of the sleeve body 1, and the flipping link 3 is arranged perpendicular to the sleeve body 1.

[0037] The effect achieved in this way is to facilitate the operation of the sleeve body 1 to perform the flipping action.
