Description

Technical Field

[0001] The invention specifically relates to a spinal tumor intraoperative radiotherapy auxiliary drilling device. Background Art

[0002] Spinal tumors are a complex disease that not only affects the structural stability of the spine, but may also compress the spinal cord and nerve roots, leading to severe neurological dysfunction such as severe intractable radicular pain and paralysis. In the surgical treatment of primary spinal tumors or metastatic tumors, intraoperative radiotherapy is an important part of the comprehensive treatment of spinal tumors. Through precise positioning and intraoperative internal irradiation, it aims to control tumor growth, relieve pain, protect nerve function and improve the quality of life of patients.

[0003] During intraoperative radiotherapy, a needle-type applicator needs to be inserted into the diseased vertebra of the spine. The applicator is precisely placed in the center of the residual tumor tissue or tumor bed to achieve local high-dose irradiation, thereby controlling tumor growth as much as possible, relieving pain and reducing the probability of spinal cord compression, ultimately achieving the goal of improving the patient's quality of life.

[0004] In the early stage of inserting the needle applicator, it is necessary to make a hole on the spine and insert a sleeve at the hole position to facilitate the insertion of the needle applicator. At the same time, it should be avoided that the vertebral bone tissue squeezes the sleeve to cause damage and degeneration, which is not conducive to the insertion of the needle applicator. However, most of the existing spinal punching devices only use a bone hammer to hammer the puncher to punch holes during the punching process. This method cannot accurately control the accuracy of the punching, including the depth and position, which affects the killing effect of tumor cells. In osteoblastic metastases, the vertebral bone is sclerotic, and it is easy to use excessive force to knock with a bone hammer, causing damage to the spinal cord or abdominal blood vessels and organs in the spinal canal. At the same time, the hammering method is also easy to cause deformation of the sleeve, affecting the removal of the sleeve and the insertion of the needle applicator. Therefore, in view of this, a radiation punching auxiliary punching device for spinal tumor surgery is proposed to solve the above technical problems. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention proposes an auxiliary punching device for intraoperative radiotherapy of spinal tumors to solve the technical problems raised in the above background technology, that is, the existing spinal punching devices mostly only punch holes by hammering the puncher with a bone hammer during the punching process, and this method cannot accurately control the depth and position of the punching, affecting the killing effect of tumor cells; and it is easy to cause excessive force during hammering, causing damage to the spinal cord or abdominal blood vessels and organs in the spinal canal, and it is easy to cause excessive force during hammering in the later stage of punching, causing damage to the inner side of the spine.

[0014] In a preferred embodiment, a detachable counterweight is provided on the hammer body.

[0015] In a preferred embodiment, the driving mechanism comprises:

[0016] A ratchet wheel is arranged at a hinge between the connecting frame and the housing;

[0017] A mounting seat, arranged on the handle, a first baffle plate is arranged in the shell, and a first elastic member is arranged between the first baffle plate and the mounting seat;

[0018] a movable frame, slidably disposed in the mounting seat, the movable frame being provided with a ratchet bar arranged along an arc, the ratchet bar being engaged with the ratchet wheel, and the ratchet bar being disengaged from the ratchet wheel when the handle is rotated to an extreme position; and

[0019] The second elastic member is arranged between the movable frame and the mounting seat.

[0020] In a preferred embodiment, a positioning block is provided on the movable frame, a positioning groove is provided on the mounting seat, and the positioning block is slidably locked in the positioning groove.

[0021] In a preferred embodiment, the mounting seat is rotatably sleeved on the connecting shaft, a limiting plate is provided at the bottom of the mounting seat, and the limiting plate abuts against the handle.

[0022] In a preferred embodiment, a sliding sleeve on the punching rod is provided with a propulsion cylinder, which abuts against the end of the tube sleeve, and the handle and the propulsion cylinder are connected through a propulsion assembly to convert the rotation of the handle away from the handle into driving the propulsion cylinder to slide.

[0023] In a preferred embodiment, the propulsion assembly comprises:

[0024] A connecting rod is arranged on the propulsion cylinder, a positioning sleeve is arranged on the housing, and the connecting rod is slidably inserted into the positioning sleeve;

[0025] A second baffle plate is disposed on the connecting rod, and a third elastic member is disposed between the second baffle plate and the inner wall of the shell; and

[0026] The roller is arranged at the end of the connecting rod, and a slope is arranged on the side of the handle close to the roller, and the roller abuts against the slope.

[0027] In a preferred embodiment, the sleeve is detachably connected to the punching rod via a connecting assembly.

[0028] In a preferred embodiment, the connection assembly includes:

[0029] Two groups of cross bars are provided, and are relatively slidably arranged in the punching rod along a direction perpendicular to the axis of the punching rod, and a fourth elastic member is arranged between the two groups of cross bars;

[0030] A wedge-shaped block is arranged on one end of the cross bar away from the housing and extends out of the punching rod. A connecting hole is provided on the sleeve, and the wedge-shaped block is clamped in the connecting hole; and

[0031] The pressing block is arranged on one end of the cross bar close to the shell body and extends out of the punching rod.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. When the punching device is in use, the punching rod is brought into contact with the spine to be radiotherapy, and a preliminary hole is punched by hammering the hammer body. When the punching rod is about to break the vertebral cortical bone, the handle is gripped to rotate along the connecting axis. The handle is converted into a driving connection frame through the driving mechanism during the rotation of the handle close to the handle, and the connection with the handle is released when the connection frame rotates to the limit position. The connection frame can be reset by the reset component, thereby driving the hammer body to hit the receiving seat, and then the inertia generated by the movement of the hammer body applies an impact force along the axial direction of the punching rod to perform a small-amplitude hole, thereby The depth of the punching can be conveniently controlled, and by adjusting the handle to control the final position of the punching rod tip, the working channel can be effectively established in the ideal position for radiotherapy, thereby achieving the effect of killing more tumor cells; at the same time, in osteoblastic metastases with vertebral bone sclerosis, the punching device can avoid excessive force caused by using a bone hammer to knock in the later stage of punching, resulting in damage to the spinal cord or abdominal blood vessels and organs in the spinal canal; after the punching is completed, the tube sleeve is placed in the established bone channel, which is convenient for radiotherapy of spinal tumors through the needle applicator from the tube sleeve.

[0034] 2. When the punching device is in use, the handle is rotated in the direction close to the handle to drive the hammer to move. After the punching is completed, the sleeve is placed in the spine. The deformation of the spinal bone tissue will squeeze the sleeve, which will make it difficult to smoothly remove the punching rod due to the deformation of the sleeve. The handle can be rotated in the direction away from the handle. During the rotation, the handle pushes the roller through the inclined surface, so that the connecting rod slides and drives the propulsion cylinder to slide, so that the punching rod and the sleeve are driven to move relative to each other through the abutment between the propulsion cylinder and the sleeve, so that the punching rod can be easily removed from the sleeve.

[0035] 3. When the punching device is in use, after the punching rod is taken out of the tube sleeve and placed into the needle applicator, the tube sleeve will be clamped due to the movement of the spinal bone tissue. The traditional method is mostly to clamp the tube sleeve with pliers to disassemble it, which will cause more serious deformation of the end of the tube sleeve, and the pliers will easily fall off the tube sleeve. The punching rod can be inserted into the tube sleeve again and the wedge-shaped block can be inserted into the connecting hole opened on the tube sleeve. Under the action of the fourth elastic member, the two groups of cross bars move in opposite directions to avoid the wedge-shaped block from falling off the connecting hole. The tube sleeve can be quickly taken out by pulling the punching device, thereby improving the efficiency of taking out the tube sleeve. After taking it out, the wedge-shaped block can be separated from the connecting hole by pressing the button, and the tube sleeve can be disassembled, which is convenient for taking out the tube sleeve after the operation.

[0051] The present invention is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Technicians in this field can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0052] Example:

[0053] like Figures 1 to 3 As shown, the present invention provides a spinal tumor intraoperative radiotherapy auxiliary punching device, including a housing 101, a handle 102 is provided on the housing 101, a punching rod 106 is provided at one end of the housing 101, a detachable sleeve 107 is sleeved on the punching rod 106, and a receiving seat 103 is provided on the side of the housing 101 away from the punching rod 106. The housing 101 is also hinged with a connecting frame 402, a hammer body 403 is provided at one end of the connecting frame 402, and a detachable counterweight block 404 is provided on the hammer body 403.

[0054] In the initial state, the hammer body 403 and the counterweight block 404 are integrated, and the counterweight block 404 is in contact with the receiving seat 103, so that the sharp end of the punching rod 106 can be moved to contact the spine, and the punching rod 106 is driven to move by hammering the hammer body 403 to perform preliminary punching, and during the punching process, the sleeve 107 follows the movement of the punching rod 106 so that its end is penetrated into the spine, and after punching, the punching rod 106 can be taken out so that the sleeve 107 remains in the spine, which is convenient for inserting the needle applicator through the sleeve 107.

[0055] like Figures 3 to 6 As shown, in this embodiment, a handle 202 is further provided on the shell 101, and a connecting shaft 201 is provided at the end of the handle 202. The connecting shaft 201 is rotatably provided on the shell 101, and a driving mechanism connected to the connecting frame 402 is provided on the handle 202. The rotation of the handle 202 close to the handle 102 is converted into driving the connecting frame 402 to rotate through the driving mechanism, and the connection with the handle 202 is released when the connecting frame 402 rotates to the extreme position.

[0056] The driving mechanism includes a ratchet 401 arranged at the hinge of the connecting frame 402 and the shell 101, a mounting seat 301 is arranged on the handle 202, a first baffle 104 is arranged in the shell 101, a first elastic member 302 is arranged between the first baffle 104 and the mounting seat 301, a movable frame 304 is slidably arranged in the mounting seat 301, a ratchet bar 307 arranged along an arc is arranged on the movable frame 304, the ratchet bar 307 is meshed with the ratchet 401, and the ratchet bar 307 is disengaged from the ratchet 401 when the handle 202 is rotated to the extreme position, and a second elastic member 305 is arranged between the movable frame 304 and the mounting seat 301.

[0057] When the grip 202 is held in the direction close to the handle 102 so as to close it with the handle 102, the grip 202 drives the mounting seat 301 to rotate during the rotation process, and under the action of the second elastic member 305, the ratchet bar 307 on the movable frame 304 is always engaged with the ratchet 401, and then the connecting frame 402 can be driven to rotate by controlling the rotation of the ratchet 401, so that the hammer body 403 is away from the receiving seat 103, and the ratchet bar 307 disengages from the ratchet 401 when the connecting frame 402 rotates to the extreme position.

[0058] like Figure 3 , 6 As shown, in this embodiment, the connecting frame 402 is connected to the housing 101 via a reset assembly. The reset assembly includes a tension spring 406 and an extension frame 405 disposed on the connecting frame 402, one end of the tension spring 406 is connected to the extension frame 405, and the other end is connected to the inner side of the housing 101.

[0059] During the movement, the connecting frame 402 drives the extension frame 405 to move to stretch the tension spring 406. After the ratchet bar 307 disengages from the ratchet wheel 401, the tension spring 406 resets and drives the connecting frame 402 to quickly reset, so that the hammer body 403 and the counterweight block 404 hammer the receiving seat 103, and the punching rod 106 continues to move to punch holes. Compared with the traditional hammering method, the inertia of the hammer body 403 and the counterweight block 404 is used for subsequent punching, so that the punching accuracy is easier to control, thereby effectively avoiding excessive hammering force that causes excessive movement of the punching rod 106 to cause damage to the inner side of the spine.

[0060] In the process of gripping the handle 202 to drive the mounting seat 301 to move, the first elastic member 302 is compressed. After the handle 202 is released, the mounting seat 301 and the handle 202 are reset under the reset ability of the first elastic member 302. During the reset of the mounting seat 301, the ratchet 401 pushes the connecting frame 402 to be retracted into the mounting seat 301 through the ratchet bar 307 to disengage from the ratchet 401. The movable frame 304 is provided with a positioning block 306, and the mounting seat 301 is provided with a positioning groove 303. The positioning block 306 is slidably clamped in the positioning groove 303. The movement of the movable frame 304 is positioned by the cooperation of the positioning block 306 and the positioning groove 303. After the handle 202 is reset, the movable frame 304 is reset under the action of the second elastic member 305, so that the ratchet bar 307 is again engaged with the ratchet 401 to prepare for the next hammering, thereby facilitating continuous hammering and improving the punching efficiency of the punching device.

[0061] like Figure 3 , 4As shown in Figures 5 and 6, in the present embodiment, the mounting seat 301 is rotatably sleeved on the connecting shaft 201, and a limiting plate 308 is provided at the bottom of the mounting seat 301, and the limiting plate 308 abuts against the grip 202, so that the grip 202 drives the mounting seat 301 to rotate by abutting against the limiting plate 308 during the process of moving toward the handle 102. When the mounting seat 301 is reset under the action of the first elastic member 302, the mounting seat 301 will not be driven to move when the grip 202 is rotated in the direction away from the handle 102.

[0062] like Figure 3 , 5 As shown in Figures 7 and 8, in this embodiment, a propulsion tube 502 is slidably sleeved on the punching rod 106, and the propulsion tube 502 abuts against the end of the tube sleeve 107. The handle 202 and the propulsion tube 502 are connected through a propulsion assembly, so as to convert the rotation of the handle 202 away from the handle 102 into driving the propulsion tube 502 to slide. The propulsion assembly includes a connecting rod 501 disposed on the propulsion tube 502, a positioning sleeve 105 is disposed on the housing 101, and the connecting rod 501 is slidably inserted into the positioning sleeve 105. A second baffle 503 is disposed on the connecting rod 501, and a third elastic member 505 is disposed between the second baffle 503 and the inner wall of the housing 101. A roller 504 is disposed at the end of the connecting rod 501, and a slope 203 is disposed on the side of the handle 202 close to the roller 504, and the roller 504 abuts against the slope 203.

[0063] When the handle 202 rotates in the direction close to the handle 102, the hammer body 403 moves. After the drilling is completed and the sleeve 107 is placed in the spine, the sleeve 107 will be squeezed due to the deformation of the spinal bone tissue, so that the punching rod 106 cannot be smoothly removed due to the deformation of the sleeve 107. The handle 202 can be rotated in the direction away from the handle 102. During the rotation process, the handle 202 pushes the roller 504 through the inclined surface 203, so that the connecting rod 501 slides and drives the push cylinder 502 to slide, so that the punching rod 106 and the sleeve 107 are driven to move relative to each other through the contact between the push cylinder 502 and the sleeve 107, so as to facilitate the removal of the punching rod 106 from the sleeve 107. The setting of the roller 504 reduces the friction force on the inclined surface 203, and prevents the handle 202 from being damaged due to long-term use.

[0064] like Figures 1 to 3As shown, in this embodiment, the sleeve 107 is detachably connected to the punching rod 106 through a connecting assembly. The connecting assembly includes two groups of cross bars 601, which are relatively slidably arranged in the punching rod 106 along a direction perpendicular to the axis of the punching rod 106, and a fourth elastic member 603 is arranged between the two groups of cross bars 601. A wedge-shaped block 604 is arranged at one end of the cross bar 601 away from the housing 101, and the wedge-shaped block 604 extends out of the punching rod 106. A connecting hole 108 is opened on the sleeve 107, and the wedge-shaped block 604 is clamped in the connecting hole 108. A pressing block 602 is also arranged at one end of the cross bar 601 close to the housing 101, and the pressing block 602 extends out of the punching rod 106.

[0065] After the punching rod 106 is taken out of the sleeve 107 and placed into the needle applicator, the movement of the spinal bone tissue will clamp the sleeve 107. The traditional method is mostly to clamp the sleeve 107 with pliers to disassemble it, which will cause serious deformation of the end of the sleeve 107, and the pliers will easily detach from the sleeve 107. The punching rod 106 can be inserted into the sleeve 107 again and the wedge-shaped block 604 can be inserted into the connecting hole 108 opened on the sleeve 107. Under the action of the fourth elastic member 603, the two groups of cross bars 601 move in opposite directions to prevent the wedge-shaped block 604 from detaching from the connecting hole 108. The sleeve 107 can be quickly removed by pulling the punching device, thereby improving the efficiency of removing the sleeve 107. After removal, the wedge-shaped block 604 can be separated from the connecting hole 108 by pressing the button 602, and the sleeve 107 can be disassembled, which is convenient for removing the sleeve 107 after the operation.

[0066] Specific usage and beneficial effects of the present invention:

[0067] When the punching device is in use, the punching rod 106 is brought into contact with the spine to be radiotherapy, and a preliminary hole is punched by hammering the hammer body 403. When the punching rod 106 is about to break the vertebral cortical bone, the handle 202 is gripped to rotate along the connecting shaft 201. The handle 202 is converted into a driving mechanism to rotate the connecting frame 402 during the process of rotating close to the handle 102, and the connection with the handle 202 is released when the connecting frame 402 rotates to the extreme position, and the connecting frame 402 can be controlled to reset by the reset component, thereby driving the hammer body 403 to hit the receiving seat 103, and then the inertia generated by the movement of the hammer body 403 is used to punch the hole. The rod 106 applies an impact force along its axial direction to perform small-amplitude drilling, thereby facilitating the control of the drilling depth. At the same time, by adjusting the grip direction to control the final position reached by the tip of the drilling rod, the working channel can be effectively established at an ideal position for radiotherapy, thereby achieving the effect of killing more tumor cells. At the same time, in osteoblastic metastases, the vertebral bone is sclerotic, and the drilling device can avoid excessive force caused by using a bone hammer to knock in the later stage of drilling, resulting in damage to the spinal cord or abdominal blood vessels and organs in the spinal canal. After the drilling is completed, the sleeve 107 is inserted into the established bone channel, which is convenient for radiotherapy of spinal tumors through the needle-type applicator from the sleeve 107.

[0068] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments. On the basis of the present invention, some modifications or improvements can be made thereto, which is obvious to those skilled in the art. Therefore, these modifications or improvements made on the basis of not departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
