Description

Technical Field

[0001] The present invention particularly relates to a surgical shearing device adaptable to different angles. Background Art

[0002] Neurosurgery is a branch of surgery. It is a high-level discipline that uses unique neurosurgery research methods to study the human nervous system, such as the brain, spinal cord and peripheral nervous system, and its related ancillary structures, such as the skull, scalp, cerebral blood vessels, meninges and other structural injuries, inflammation, tumors, malformations and certain genetic metabolic disorders or functional disorders, such as epilepsy, Parkinson's disease, neuralgia and other diseases, and explores new diagnosis, treatment and prevention technologies.

[0003] In neurosurgery, it is often necessary to cut the arachnoid membrane in the patient's skull to clearly expose the relevant anatomical structures. The operating space is limited, especially for endoscopic surgery, which requires higher precision. Currently, doctors often use spring scissors to cut tissues such as the arachnoid membrane. However, due to the particularity of brain tissue and the low flexibility of existing scissors, doctors need to constantly change their hands to cut the target tissue, and the relative position of the patient can make the scissors contact the tissue to be cut at a suitable angle, which greatly reduces the doctor's efficiency and increases the difficulty of the operation. In some parts, the existing scissors cannot adapt at all, which greatly slows down the operation and increases the risk of trauma. Summary of the invention

DETAILED DESCRIPTION

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the invention is not limited by the specific implementation disclosed below.

[0034] See also Figures 1 to 5 The present invention discloses a surgical shearing device adapted to different angles, including an operating handle 100, an adapter 200, a support rod 300, a mounting head 400, scissors 500, a rotation drive mechanism 600 and an opening and closing drive mechanism 700.

[0035] Specifically, the support rod 300 includes a support rod 310 and an angle adjustment member 320. Multiple support rods 310 are hinged in sequence through the angle adjustment member 320. The end of the support rod 310 at the head end is fixedly connected to the adapter 200, and the angle adjustment member 320 can adjust and lock the angle between the two support rods 310 connected thereto, so that the end of the entire support rod 300 can be adjusted arbitrarily in the up and down, left and right positions.

[0036] The mounting head 400 is disposed at the end of the support rod 310 at the rear end. The scissors 500 include two blades, which are hinged to the mounting head 400 in opposite directions. The rotation drive mechanism 600 is connected to the mounting head 400 and is used to drive the mounting head 400 to rotate around the central axis 321 of the support rod 310 connected thereto. The opening and closing drive mechanism 700 is connected to the two blades and is used to drive the two blades to separate or close from each other for cutting.

[0037] When in use, one hand holds the operating handle 100, and the other hand uses the angle adjustment member 320 to adjust the spatial position of the end of the support rod 300, i.e., the mounting head 400, over a large range according to the target position, so that the scissors 500 are as close to the destination as possible. Then, the mounting head 400 is driven to rotate by the rotary drive mechanism 600 to adjust the direction of the blades of the scissors 500, and finally, the opening and closing drive mechanism 700 is used to drive the two blades to separate or close from each other for cutting.

[0038] By using the above-mentioned surgical shearing device that can adapt to different angles, the position of the scissors 500 is adjusted by the support rod 300, and the cutting angle of the blade is adjusted at a close distance by the rotary drive mechanism 600. It is no longer necessary to constantly change the hand during the operation to cut the target tissue, thereby greatly improving the doctor's efficiency and reducing the difficulty of the operation. At the same time, since the support rod 300 and the rotary drive mechanism 600 are flexible to adjust, they can greatly adapt to the needs of different surgical positions, thereby improving the success rate of the operation.

[0039] In this embodiment, there are three support rods 310, and the angle adjustment member 320 includes a central shaft 321, an internal gear, and an external gear 322. Two adjacent support rods 310 are hinged by the central shaft 321, and the central shafts 321 at both ends of the same support rod 310 intersect each other at 90 degrees. The internal gear is set in the shaft hole of one of the two adjacent support rods 310, and the central shaft 321 is fixed to the other support rod 310 and can be slidably inserted in the internal gear. The external gear 322 is sleeved and fixed on the central shaft 321, and the central shaft 321 is slidable, and the external gear 322 can be inserted in the internal gear and mesh with the internal gear.

[0040] When in use, the two center axes 321 can be made parallel to the ground and perpendicular to the ground respectively. When the support rod 310 is pushed axially along the center axis 321 to disengage the inner gear and the outer gear 322 from each other, the support rod 310 can be rotated around the center axis 321. After rotating to the required angle, the support rod 310 is slid along the center axis 321 until the inner gear and the outer gear 322 are re-engaged, thereby completing the position adjustment of the mounting head 400.

[0041] As a preferred embodiment, the angle adjustment member 320 further includes a first elastic member 323, which is sleeved on the central axis 321 and abuts between the two. When the first elastic member 323 is in a natural state, the outer gear 322 is meshed with the inner gear. When the angle of the support rod 310 needs to be adjusted, the support rod 310 is pressed along the direction of the central axis 321 until the inner and outer gears 322 are disengaged from each other. After release, the support rod 310 is driven to slide along the direction of the central axis 321 under the action of the restoring force of the first elastic member 323 until the inner and outer gears are meshed again.

[0042] In this embodiment, the opening and closing driving mechanism 700 includes a fixed handle 110, a movable handle 120, a guide cylinder 710, a first pulling rope 720 and a second elastic member 730. The adapter 200 and the support rod 310 are both hollow members. The fixed handle 110 is fixed on the adapter 200, and the end of the movable handle 120 extends from the outer end of the adapter 200 into the adapter 200 and is hinged with the adapter 200. The guide cylinder 710 is coaxially arranged with the mounting head 400 and fixed in the mounting head 400. The ends of the two blades extending into the mounting head 400 are connecting ends, and the two connecting ends diverge outward from each other. There are two first pulling ropes 720, and the ends of the two first pulling ropes 720 are respectively connected to the two connecting sections, and the two first pulling ropes 720 simultaneously pass through the guide cylinder 710 and are connected to the end of the movable handle 120 extending into the adapter 200. The second elastic member 730 is supported between the two connecting ends.

[0043] During use, in the normal state, the second elastic member 730 stretches the two connecting ends apart, and the two blades are in a closed state. When cutting is required, the movable handle 120 is pressed, and the movable handle 120 pulls the two first pulling ropes 720 to move backward, which can drive the two connecting ends to close, and then drive the two blades to separate. In addition, the second elastic member 730 is in a compressed state. When the pressure on the movable handle 120 is reduced, the two blades are closed under the action of the restoring force of the second elastic member 730 to produce a cutting action.

[0044] The above-mentioned opening and closing driving mechanism 700 can be used to conveniently drive the blade to perform cutting action.

[0045] As a preferred embodiment, the opening and closing drive mechanism 600 also includes a first pulley 740. There are two first pulleys 740. The two first pulleys 740 are installed at one end of the guide cylinder 710 close to the blade. The two first pulling ropes 720 respectively pass around the two first pulleys 740 and then extend into the guide cylinder 710.

[0046] When in use, the first pulling rope 720 is conveniently guided by the pulley, thereby facilitating the sliding of the first pulling rope 720.

[0047] In this embodiment, the rotary drive mechanism 600 includes a rotary power source 610, a driving gear 620 and an internal gear 630. A mounting plate is provided inside the support rod 310 connected to the mounting head 400, the driving gear 620 is rotatably fixed on the mounting plate and extends into the mounting head 400, and the internal gear 630 is sleeved and fixed on the inner wall of the mounting head 400 and meshes with the driving gear 620. The rotary power source 610 is fixed on the mounting plate and is used to drive the driving gear 620 to rotate forward or reverse.

[0048] Specifically, the rotary power source 610 includes a push plate 611, a third elastic member 612, a bar gear 613, a driven gear 614, a first bevel gear 615, a second bevel gear 616, a second pulling rope 617 and a winding device 618. The push plate 611 is mounted on the mounting plate through the third elastic member 612 and is located on a side away from the mounting head 400. A guide groove in the same direction as the central axis 321 of the mounting head 400 is provided on the mounting plate, and the bar gear 613 can be slidably inserted in the guide groove. The driven gear 614 can be rotatably fixed on the mounting plate and meshed with the bar gear 613. The first bevel gear 615 is sleeved and fixed on the central axis 321 of the driven gear. The second bevel gear 616 is sleeved and fixed on the central axis 321 of the driving gear 620. One end of the second pulling rope 617 is connected to the push plate 611, and the other end extends along the support rod 300 directly into the adapter 200. The wire reel 618 is disposed on the adapter 200. The end of the second pulling rope 617 is wound around the wire reel 618, and the wire reel 618 can be used for winding or releasing the wire.

[0049] When the angle of the mounting head 400 needs to be adjusted, it is only necessary to reel in or unreel the wire through the wire winder 618. When reeling in the wire, the bar teeth 613 can be driven to move backward, thereby driving the driven gear 614 to rotate, and then the first bevel gear 615 and the driving gear 620 rotate, thereby driving the internal gear 630 to rotate, and finally driving the mounting head 400 to rotate; at the same time, the third elastic member 612 is stretched.

[0050] When the wire winder 618 is unwinding, the third elastic member 612 retracts and restores, driving the bar gear 613 forward, which can then rotate in the opposite direction through the first bevel gear 615, the driving gear 620, and the inner gear 630, thereby driving the mounting head 400 to rotate in the opposite direction.

[0051] In this embodiment, the wire winder 618 includes a driving disk 6181, a wire winding disk 6182, a stop pin 6183 and an elastic pusher 6184. The driving disk 6181 and the wire winding disk 6182 are coaxially arranged through a rotating shaft, and the rotating shaft is rotatably connected to the side wall of the mounting head 400, and the driving disk 6181 is located outside the mounting head 400. The wire winding disk 6182 is located inside the mounting head 400. The second pulling rope 617 is wound around the wire winding disk 6182. A plurality of pits are arranged at intervals in the circumferential direction on the driving disk 6181.

[0052] The outer wall of the adapter 200 is provided with a mounting block, and a plug hole extending along the radial direction of the drive disk 6181 is provided in the mounting block. The end of the limit pin 6183 close to the drive disk is a spherical head, and the limit pin can be slidably inserted into the plug hole. The elastic pusher 6184 is arranged in the plug hole and is arranged between the limit pin 6183 and the plug hole. Under the action of the elastic pusher 6184, the spherical head is inserted into one of the pits. When the drive disk is driven to rotate by external force, the spherical head can slide out of the pit.

[0053] During use, in the normal state, since the limit pin 6183 is inserted in the groove, the driving disk 6181 cannot rotate. The medical staff only needs to use their fingers to move the driving disk 6181 forward or reversely, and the spherical head is forced to leave the pit, which can drive the winding disk 6182 to reel in or release the wire, thereby completing the rotation angle adjustment of the mounting head 400.

[0054] By using the above-mentioned surgical shearing device that can adapt to different angles, the position of the scissors 500 is adjusted by the support rod 300, and the cutting angle of the blade is adjusted at a close distance by the rotary drive mechanism 600. It is no longer necessary to constantly change the hand during the operation to cut the target tissue, thereby greatly improving the doctor's efficiency and reducing the difficulty of the operation. At the same time, since the support rod 300 and the rotary drive mechanism 600 are flexible to adjust, they can greatly adapt to the needs of different surgical positions, thereby improving the success rate of the operation.
