Description

Technical Field

[0001] The present invention relates to the technical field of minimally invasive orthopedic surgery, and in particular to a multi-degree-of-freedom minimally invasive orthopedic surgical instrument. Background Art

[0002] Minimally invasive surgery is a surgical procedure performed with minimal trauma, aiming to achieve optimal therapeutic effects with minimal physiological disturbance. Currently, minimally invasive surgery has been widely used in clinical surgery. Compared with traditional open surgery, it has the advantages of smaller incisions, less bleeding, smaller postoperative scars, and shorter recovery time. However, traditional minimally invasive surgery usually uses one or two slender long rods to perform related surgical actions such as stripping and clamping. Due to space and structural limitations, traditional minimally invasive surgical tools have poor flexibility and coordination, which increases the doctor's labor intensity and thus increases the difficulty of the doctor's work.

[0003] Therefore, there is an urgent need for a multi-degree-of-freedom minimally invasive orthopedic surgical instrument to solve the above-mentioned problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a multi-degree-of-freedom minimally invasive orthopedic surgical instrument. The device can easily perform related surgical actions such as stripping and clamping in narrow wounds through the cooperation of a multi-directional rotating clamping head, an inserting protective tube, and a driving control handle structure. At the same time, the multi-directional rotating clamping head of the device has good flexibility and coordination, thereby reducing the doctor's labor intensity and thus reducing the difficulty of the doctor's work.

[0005] The present invention provides a multi-degree-of-freedom minimally invasive orthopedic surgical instrument, comprising: A multi-directional rotating clamping head is hinged on the head end of the probe protection tube and is used to penetrate into the minimally invasive incision to perform detailed treatment on the designated wound site; A drive control handle structure is provided on the tail end of the probe protection tube, the internal structure of the drive control handle structure is connected to the multi-directional rotating clamping head, and the drive control handle structure is used for hand-holding and provides driving force for the operation of the multi-directional rotating clamping head.

[0006] Furthermore, the multi-directional rotating clamping head includes a fixed seat, a first clamping jaw rotatably hinged on the fixed seat, and a second clamping jaw rotatably hinged on the fixed seat, and the fixed seat is rotatably hinged at the head end of the insertion protection tube.

[0007] Furthermore, a first opening slot is provided on the outer side of the first clamping jaw, a first opening connecting column is provided in the first opening slot, a first clamping slot is provided on the inner side of the first clamping jaw, and a first clamping connecting column is provided in the first clamping slot.

[0008] Furthermore, a second opening slot is provided on the outer side of the second clamping jaw, a second opening connecting column is provided in the second opening slot, a second clamping slot is provided on the inner side of the second clamping jaw, and a second clamping connecting column is provided in the second clamping slot.

[0009] Furthermore, the drive control handle structure includes a protective storage box, a handheld handle arranged on the lower surface of the protective storage box, a clamping drive assembly arranged in the protective storage box, an opening drive assembly arranged in the protective storage box, and a swinging drive assembly arranged in the protective storage box.

[0010] Furthermore, the clamping drive assembly includes a connecting block, a first pulling wire arranged on the connecting block, a connecting and fixing column arranged at the end of the first pulling wire, and a sliding pulling ring arranged on the lower end surface of the connecting and fixing column. The connecting block can be rotatably mounted on the first clamping connecting column and the second clamping connecting column.

[0011] Furthermore, the sliding pull ring is slidably inserted into the bottom of the protective storage box and is embedded therein. A sliding embedding block is provided between the sliding pull ring and the connecting and fixing column. A sliding embedding groove adapted to the sliding embedding block is provided through the bottom of the protective storage box.

[0012] Furthermore, the opening drive assembly includes a first hand-tightened damping winding wheel rotatably arranged on the protective storage box, a second hand-tightened damping winding wheel rotatably arranged on the protective storage box and located next to the first hand-tightened damping winding wheel, a second pulling wire fixedly wound on the first hand-tightened damping winding wheel, a first buckle arranged at the end of the second pulling wire, a third pulling wire fixedly wound on the second hand-tightened damping winding wheel, and a second buckle arranged at the end of the third pulling wire, the first buckle rotatably sleeved on the first opening connecting column, and the second buckle rotatably sleeved on the second opening connecting column.

[0013] Furthermore, the swing drive assembly includes a first sprocket arranged on the fixed seat, a hand-tightening rotating block rotatably arranged on the protective storage box, a second sprocket embedded in the hand-tightening rotating block, and a connecting chain sleeved on the first sprocket and the second sprocket.

[0014] The present invention also provides an operating method of a multi-degree-of-freedom minimally invasive orthopedic surgical instrument, comprising the following steps: S1. The device should be used in conjunction with an endoscope. The endoscope should be inserted through the minimally invasive incision first, and the operator should observe the specific situation. Then, the operator should hold the handheld handle with one hand and insert the multi-directional rotating gripping head of the device through the minimally invasive incision. S2. When the multi-directional rotating clamping head starts to work, the operator holds the handheld handle with one hand and slowly pushes the multi-directional rotating clamping head of the device to the working area. Then, the operator can use the other hand to turn the first hand-tightened damping reel, and then turn the second hand-tightened damping reel. At this time, the second pulling wire and the third pulling wire will be slowly tightened. At this time, under the pulling of the second pulling wire and the third pulling wire, and because the first clamping jaw and the second clamping jaw are rotatably hinged on the fixed seat, the first clamping jaw and the second clamping jaw will slowly open until the angle between the first clamping jaw and the second clamping jaw is opened to the desired angle; S3. At this time, the operator can push the opened first and second clamping jaws to the working point. At this time, the index finger of the hand holding the handheld handle can be used to hook the sliding pull ring and pull it. At this time, the sliding pull ring is forced to slide closer to the handheld handle, and then the first pulling wire is tightened by the tension. At this time, the first pulling wire will pull the connecting block to move toward the handheld handle. At this time, because the first and second clamping jaws are rotated and hinged on the fixed base, the first and second clamping jaws will approach each other and clamp the object to be clamped, thereby completing the clamping of the designated object; S4. When the first clamping jaw and the second clamping jaw are close to each other and clamped, the second pulling wire and the third pulling wire will also be subjected to a pulling force. At this time, because the operator does not manually turn the first hand-tightened damping reel and the second hand-tightened damping reel, the first hand-tightened damping reel and the second hand-tightened damping reel will automatically unwind the second pulling wire and the third pulling wire. However, there will be some damping during unwinding to prevent the second pulling wire and the third pulling wire from spreading. When the clamping drive assembly is working, the opening drive assembly will not cause any obstruction to the clamping drive assembly. S5. When the multi-directional rotating clamping head needs to bend left or right, the operator needs to manually twist the hand-tightening rotating block. At this time, the hand-tightening rotating block will rotate as a whole. At this time, the second sprocket will rotate together with the hand-tightening rotating block. Then, under the action of the connecting chain and the first sprocket, the fixed seat can achieve a large-scale rotation left or right. The first hand-tightening damping reel, the second hand-tightening damping reel and the sliding pulling ring are not locked. Therefore, when the multi-directional rotating clamping head bends left or right, the first pulling wire, the second pulling wire and the third pulling wire will be moderately pulled. Loose, so when the swing drive assembly is operating, the clamping drive assembly and the opening drive assembly will not affect the swing drive assembly. After the multi-directional rotating clamping head is bent left or right, the clamping drive assembly and the opening drive assembly can still operate normally, because the first pulling wire, the second pulling wire and the third pulling wire are all flexible, but when the multi-directional rotating clamping head is bent left or right, the multi-directional rotating clamping head can only open the first clamping jaw or the second clamping jaw alone when opening, and it is the one opposite to the bending direction, but this does not affect the overall operation effect.

[0015] The present invention provides a multi-degree-of-freedom minimally invasive orthopedic surgical instrument that can easily perform stripping, clamping, and other related surgical actions in narrow wounds through the cooperation of a multi-directional rotating clamping head, an inserting protective tube, and a driving control handle structure. At the same time, the multi-directional rotating clamping head of the device has good flexibility and coordination, thereby reducing the doctor's labor intensity and thus reducing the difficulty of the doctor's work.

[0016] The present invention provides a multi-degree-of-freedom minimally invasive orthopedic surgical instrument, which can achieve multi-directional rotation control of the multi-directional rotating clamping head using a purely mechanical structure through the mutual cooperation of the azimuthally rotating clamping head, the insertion protection tube, and the drive control handle structure, thereby making the device have the characteristics of low manufacturing cost, simple structure, and easy use.

The first sprocket 31, the hand-tightening rotating block 32, the second sprocket 33 and the connecting chain 34 cooperate with each other to facilitate the left and right bending of the multi-directional rotating clamping head 1.

[0037] The working principle and use process of the present invention: S1. The device should be used together with an endoscope. When in use, the endoscope should be inserted through the minimally invasive incision first, and then the operator should observe the specific situation. Then, the operator should hold the handheld handle 16 with one hand and then insert the multi-directional rotating clamping head 1 of the device through the minimally invasive incision; S2. When the multi-directional rotating clamping head 1 starts to work, the operator holds the hand-held handle 16 with one hand and slowly pushes the multi-directional rotating clamping head 1 of the device to the working area. Then, the operator can use the other hand to twist the first hand-twisted damping winding wheel 26, and then twist the second hand-twisted damping winding wheel 27. At this time, the second pulling wire 28 and the third pulling wire 35 will be slowly tightened. At this time, under the pulling of the second pulling wire 28 and the third pulling wire 35, and because the first clamping jaw 5 and the second clamping jaw 6 are rotated and hinged on the fixed seat 4, the first clamping jaw 5 and the second clamping jaw 6 will slowly open until the angle between the first clamping jaw 5 and the second clamping jaw 6 is opened to the desired angle; S3. At this time, the operator can push the opened first clamping jaw 5 and the second clamping jaw 6 to the working point. At this time, the index finger of the hand holding the hand-held handle 16 can be used to hook the sliding pull ring 23 and pull it. At this time, the sliding pull ring 23 is forced to slide closer to the hand-held handle 16, and then the first pulling wire 21 is tightened by the tension. At this time, the first pulling wire 21 will pull the connecting block 20 to move toward the hand-held handle 16. At this time, because the first clamping jaw 5 and the second clamping jaw 6 are rotated and hinged on the fixed base 4, the first clamping jaw 5 and the second clamping jaw 6 will approach each other and clamp the object to be clamped, thereby completing the clamping of the designated object; S4. When the first clamping jaw 5 and the second clamping jaw 6 are close to each other and clamped, the second pulling wire 28 and the third pulling wire 35 will also be subjected to a pulling force. At this time, because the operator does not manually turn the first hand-tightened damping reel 26 and the second hand-tightened damping reel 27, the first hand-tightened damping reel 26 and the second hand-tightened damping reel 27 will automatically unwind the second pulling wire 28 and the third pulling wire 35. However, there will be some damping during unwinding to prevent the second pulling wire 28 and the third pulling wire 35 from spreading. When the clamping drive assembly 17 is working, the opening drive assembly 18 will not hinder the clamping drive assembly 17; S5. When the multi-directional rotating clamping head 1 needs to bend left or right, the operator needs to manually twist the hand-tightening rotating block 32. At this time, the hand-tightening rotating block 32 will rotate as a whole. At this time, the second sprocket 33 will rotate together with the hand-tightening rotating block 32. Then, under the action of the connecting chain 34 and the first sprocket 31, the fixed seat 4 can be rotated left or right. The first hand-tightening damping winding wheel 26, the second hand-tightening damping winding wheel 27 and the sliding pulling ring 23 are not locked. Therefore, when the multi-directional rotating clamping head 1 is bent left or right, the first pulling wire 21, the second pulling wire 28 and the third pulling wire 35 will all be It is moderately loose, so when the swing drive assembly 19 is operating, the clamping drive assembly 17 and the opening drive assembly 18 will not affect the swing drive assembly 19. After the multi-directional rotating clamping head 1 is bent left or right, the clamping drive assembly 17 and the opening drive assembly 18 can still operate normally, because the first pulling wire 21, the second pulling wire 28 and the third pulling wire 35 are all flexible. It is just that after the multi-directional rotating clamping head 1 is bent left or right, the multi-directional rotating clamping head 1 can only open the first clamping jaw 5 or the second clamping jaw 6 alone when opening, and it is the one opposite to the bending direction, but this does not affect the overall operation effect.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
