Description

Technical Field

[0001] The present invention specifically relates to a spinal tumor radiotherapy auxiliary 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] Before inserting the needle applicator, a hole needs to be made on the spine and a tube sleeve is inserted at the hole position to facilitate the insertion of the needle applicator. After the operation is completed, the tube sleeve needs to be removed. The existing clinical tube sleeve removal method mainly adopts clamping the tail end of the tube sleeve with a clamp, and then manually pulling the clamp back to pull out the tube sleeve. This method has the following problems:

[0005] 1. Due to the compression and wrapping of vertebral bone tissue, medical staff need to use greater force to pull out the tube sleeve, which is particularly time-consuming and labor-intensive;

[0006] 2. During the manual extraction process, the force direction cannot be guaranteed to be consistent and parallel to the axial direction of the sleeve, so left and right swinging is likely to occur. This swinging phenomenon is likely to squeeze the tissues around the spinal foramen, causing the hole to expand and causing secondary damage to the spine. Summary of the invention

[0007] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a spinal tumor radiotherapy auxiliary device, which can easily remove the inserted tube sleeve after spinal tumor radiotherapy and reduce further damage to human tissue.

The bolt has a round shank to contact with the two said adjusting bases. The bolt has a round shank to contact with the two said adjusting bases. The bolt has a round shank to contact with the two said adjusting bases.

[0016] The driving member is connected to the rotating disk and is used to drive the rotating disk to rotate. When the rotating disk rotates, the sliding rod can be driven to slide toward the center or outward through the arc-shaped guide groove and the sliding groove.

DETAILED DESCRIPTION

[0033] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0034] See also Figures 1 to 3 The present invention provides a spinal tumor radiotherapy auxiliary device, including a support platform 100, a clamping member 200 and a pulling member 300.

[0035] Specifically, the support platform 100 can be supported on the operating table 1, and the top surface of the support platform 100 is the support surface. The clamping member 200 can be clamped and fixed on the top of the tube sleeve 2; the pulling member 300 is arranged on the support platform 100 and connected to the clamping member 200, and is used to drive the clamping member 200 to move in a direction parallel to the axis of the tube sleeve 2.

[0036] When in use, the support platform 100 is first fixed on the operating bed 1, and then the end of the tube sleeve 2 is clamped by the clamping member 200, and finally the pulling member 300 is started. The pulling member 300 drives the clamping member 200 to move parallel to the axis, so that the tube sleeve 2 can be pulled out.

[0037] By adopting the above device, since the surgeon does not need to manually perform the tube removal operation, the labor intensity of the surgeon can be reduced. At the same time, through the present device, the force direction can be ensured to be consistent and parallel to the axis of the tube sleeve 2 during the tube removal process, and there will be no left and right swinging phenomenon, thereby avoiding squeezing of the surrounding tissues of the spinal foramen, causing the hole to expand, and then causing a second injury to the spine.

[0038] In this embodiment, the support platform 100 includes a support plate 110, a support rod 120 and a fixing clamp 130. The top surface of the support plate 110 is a support surface. A guide hole perpendicular to the support surface and extending from top to bottom is provided on the support plate 110. The diameter of the guide hole is adapted to the sleeve 2, and the sleeve 2 can slide through the guide hole. There are four support rods 120, and the length of the support rods 120 is adjustable. The four support rods 120 are arranged opposite to each other in pairs. The top end of the support rod 120 is hinged to the bottom surface of the support plate 110. The fixing clamp 130 can be clamped and fixed on the operating bed 1.

[0039] When in use, firstly pass the end of the tube sleeve 2 through the guide hole. Through the function of the guide hole, the support surface can be made perpendicular to the tube sleeve 2. Then, the fixing clip 130 is clamped and fixed on the operating bed 1.

[0040] In a specific implementation, a ball 140 may be further arranged in the guide hole, and the ball 140 may be connected to the pipe sleeve 2 by rolling, so that the insertion of the pipe sleeve 2 may be facilitated.

[0041] In this embodiment, the support rod 120 includes a sleeve rod and a locking screw that are plugged in sequence. The sleeve rod at the bottom is fixed to the fixing clamp, and the sleeve rod at the top is hinged to the support plate. The locking screw is threadedly connected to the sleeve rod. When the locking screw is rotated, the end of the locking screw can be pressed against the outer wall of the inner sleeve rod. When in use, first loosen the locking screw, and after the support plate 110 is sleeved on the pipe sleeve 2, adjust the length and angle of the support rod 120 as needed, and finally fix the locking screw.

[0042] In this embodiment, the clamping member 200 includes a mounting plate 210, a slide bar 220, a latch 230, a rotating plate 240 and a driving member 260. The mounting plate 210 is mounted on a supporting surface by a pulling member 300. The pulling member 300 can drive the mounting plate 210 to move vertically up and down relative to the mounting surface. The mounting plate 210 is provided with a plurality of slide grooves along its radial direction, and a slide bar 220 is provided in each slide groove and can slide in the slide groove, and the end of the slide bar 220 can extend into the inner hole of the mounting plate 210.

[0043] The rotating disk 240 is coaxially arranged with the mounting disk 210, and the rotating disk 240 and the mounting disk 210 are rotatably connected. A plurality of arc-shaped guide grooves are circumferentially spaced apart on the rotating disk 240, and one end of the arc-shaped guide groove is offset toward the center thereof. A latch 230 is arranged on each slide bar 220, and the latch 230 can be slidably clamped in the arc-shaped guide groove.

[0044] The driving member 260 is connected to the rotating disk 240 and is used to drive the rotating disk 240 to rotate. When the rotating disk 240 rotates, the sliding rod 220 can be driven to slide toward the center or outward through the arc guide groove and the sliding groove. A pressure plate 250 is provided at the end of each sliding rod 220. The pressure plate 250 extends toward the support plate 110 and can be pressed against the side wall of the pipe sleeve 2.

[0045] During use, when the driving member 260 starts the rotating disk 240 to rotate clockwise, the sliding rod 220 can be driven to slide inwards under the combined action of the arc-shaped guide groove and the sliding groove, and conversely, the sliding rod 220 can be driven to slide outwards.

[0046] It should be noted that, in the present embodiment, the pressure plate 250 can be pressed against the inner wall or outer wall of the pipe sleeve 2 when driven by the slide rod 220. When the initial position of the pressure plate 250 is within the inner diameter range of the pipe sleeve 2, if the slide rod 220 slides outward, it can be pressed against the inner wall of the pipe sleeve 2, thereby supporting the pipe sleeve 2 outward. On the contrary, when the initial position of the pressure plate 250 is outside the pipe sleeve 2, when the slide rod 220 slides inward, it can be pressed against the outer wall of the pipe sleeve 2, thereby pressing the pipe sleeve 2 outward.

[0047] In this embodiment, the driving member 260 includes a rotational power source 261, a first gear 262 and a second gear 263. The rotational power source 261 is disposed on the mounting plate 210 to drive the first gear 262 to rotate. The second gear 263 is sleeved and fixed on the rotating plate 240 and meshes with the first gear 262.

[0048] The rotating power source 261 may be a rotating motor. When the rotating power source 261 drives the second gear 263 to rotate, the first gear 262 may be driven to rotate, thereby driving the rotating disk 240 to rotate, thereby driving the sliding rod 220 to move.

[0049] As a preferred embodiment, the pressing plate 250 is pressed against the inner wall of the pipe sleeve 2, and further comprises an auxiliary clamping member 400, which is used to clamp and fix the outer wall of the pipe sleeve 2. Through the inner and outer clamping cooperation mode, the pipe sleeve 2 can be prevented from being deformed by clamping.

[0050] Specifically, the auxiliary clamping member 400 includes an annular airbag 410 and an inflator 420. An annular groove is formed on the inner wall of the mounting plate 210, the annular airbag 410 is embedded in the groove, and the inflator 420 is connected to the airbag to inflate the annular airbag 410.

[0051] During use, when the pressing plate 250 is pressed against the inner wall of the tube sleeve 2, the inflation device 420 can be started at the same time to inflate the airbag, so that the annular airbag 410 hugs the outer wall of the tube sleeve 2, forming an internal and external clamping effect on the tube sleeve 2, thereby preventing the tube sleeve 2 from deforming and improving the internal and external clamping force to prevent relative sliding with the tube sleeve 2 during pulling, which causes unsuccessful tube removal.

[0052] In this embodiment, the pulling member 300 includes a plurality of lifting mechanisms 310, which are circumferentially spaced apart on a support surface and supported on a mounting plate 210. When the lifting mechanisms 310 of the mounting plate 210 act simultaneously, the mounting plate 210 can be driven to rise and fall vertically.

[0053] When in use, the pipe can be removed by starting four lifting mechanisms 310 to drive the mounting plate 210 to rise. The lifting mechanism 310 can be a commonly used mechanism capable of linear lifting in the prior art, such as a jack.

[0054] In addition, the pulling member 300 further includes a guide rod 320 , which is vertically disposed on the support plate and perpendicular to the mounting surface and can slide through the mounting plate 210 .

[0055] The guidance of the guide rod 320 further improves the movement stability of the mounting plate 210 .

[0056] When using the above-mentioned spinal tumor radiotherapy auxiliary device, first pass the end of the tube sleeve through the guide hole, then clamp the clamp 200 and fix it on the operating table 1, then start the rotating power source and the inflation device 420, so that the pressure plate 250 and the airbag are tightly attached to the inner and outer walls of the tube sleeve 2, and finally start the lifting mechanism 310 to remove the tube.

[0057] By adopting the above device, the surgeon does not need to manually perform the tube removal operation, which can reduce the labor intensity of the surgeon. At the same time, since the force direction can be ensured to be consistent and parallel to the axis of the tube sleeve 2 during the tube removal process, there will be no left and right swinging phenomenon, thereby avoiding squeezing the surrounding tissues of the spinal foramen, causing the hole to expand, and causing secondary damage to the spine.

[0058] 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 replace some or all of the technical features therein by equivalents.
