Description

Technical Field

[0001] The invention belongs to the technical field of medical auxiliary equipment, and in particular relates to a shoulder pulling and fixing device for trigeminal neuralgia MVD surgery. Background Art

[0002] Trigeminal neuralgia is a common cranial nerve disease, which is mainly manifested by recurrent paroxysmal severe pain in the distribution area of ​​the facial trigeminal nerve. This pain is often described as electric shock-like, knife-like or tearing-like, causing great pain to patients. Microvascular decompression (MVD) is currently an effective surgical method for the treatment of trigeminal neuralgia. This surgery mainly aims to treat pain by pushing the blood vessels that compress the trigeminal nerve away from the nerve, relieving the compression of the nerve by the blood vessels. During the operation, the patient's position is very critical. Usually in MVD surgery, the patient needs to be in the side-lying position. This position helps the surgeon to better expose the surgical area, accurately find the blood vessels that compress the nerve and perform the operation. In the side-lying position, in order to maintain the stability of the patient's body and good exposure of the surgical field, the patient's shoulders and other parts need to be properly fixed.

[0003] Some existing fixation devices are not flexible enough in adjusting angles and tightness. Due to differences in body shape, shoulder width, etc. among different patients, if the fixation device cannot adapt to these differences well, it cannot provide the best fixation effect. For patients of different heights and weights, it is impossible to effectively adjust the fixation position and range, resulting in unstable fixation. In addition, when supporting the patient's head, different patients have different physical conditions, and the height and length of their heads are different when lying on their sides. The existing device cannot be adjusted according to the patient's condition to provide the best comfort, resulting in displacement of the patient due to discomfort during surgery, increasing surgical risks.

[0004] Therefore, in view of the above-mentioned existing technical problems, the present invention proposes a shoulder pulling and fixing device for trigeminal neuralgia MVD surgery. Summary of the invention

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Example 1

[0033] like Figure 1 , 3 -5, the shoulder pull assembly 2 includes a longitudinal adjustment mechanism, a transverse adjustment mechanism, a shoulder pull slider 210, a sliding plate 211, a limiting seat 212, a pull strap swivel 213, a pull strap groove 214, a forearm fixing strap 215, a shoulder pull strap 1 216, and a shoulder pull strap 217; the longitudinal adjustment mechanism is arranged at the upper end of the transverse adjustment mechanism; the shoulder pull slider 210 is symmetrically arranged at both ends of the longitudinal adjustment mechanism; the sliding plate 211 is arranged at the upper end of the shoulder pull slider 210; the limiting seat 212 is arranged at the upper end of the sliding plate 211; the two sides of the rear end of the limiting seat 212 are respectively provided with pull strap swivels 213 for rotatably connecting the shoulder pull strap 1 216 and the shoulder pull strap 217, and the upper end is provided with a pull strap groove 214 for movably connecting the forearm fixing strap 215; the forearm fixing strap 215, the shoulder pull strap 1 216, and the shoulder pull strap 217 are all elastic straps;

[0034] The longitudinal adjustment mechanism includes a longitudinal motor 201, a longitudinal screw 202, a longitudinal slider 203, and a sliding rod 204; the longitudinal motor 201 is provided with a longitudinal screw 202 at the front end; the longitudinal screw 202 is threadedly connected to the longitudinal slider 203; sliding rods 204 are symmetrically provided on both sides of the longitudinal slider 203 and are slidably connected to the shoulder slider 210;

[0035] The transverse adjustment mechanism includes a transverse motor 205, a transverse slider 206, a transverse screw 207, a transverse connecting rod 208, and a transverse sliding groove 209; a transverse connecting rod 208 is arranged at the front end of the transverse motor 205; transverse screws 207 are symmetrically arranged on both sides of the transverse connecting rod 208 and are threadedly connected to the transverse slider 206; a transverse sliding groove 209 is arranged at the front end of the transverse sliding block and is slidably connected to the shoulder slider 210; the transverse screws 207 on both sides of the transverse connecting rod 208 have the same thread pitch and opposite thread rotation directions;

[0036] The support assembly 1 includes a bed 101, a support column 102, a shoulder pad 103, a hand rest 104, and a shoulder pull slot 105; the support column 102 is arranged at the bottom of the bed 101, a slot is provided in the middle to arrange the shoulder pull assembly 2, a shoulder pull slot 105 is provided at the upper end of the middle to be slidably connected to the sliding plate 211, a shoulder pad 103 is arranged at the front end of the shoulder pull assembly 2, a hand rest 104 is arranged at the front end of the shoulder pad 103, and a head assembly 3 is arranged at the top of the bed 101;

[0037] In this embodiment, the working principle of the shoulder pulling assembly 2 is: the rotation of the longitudinal motor 201 drives the longitudinal screw 202 at the front end to rotate. Since the longitudinal screw 202 and the longitudinal slider 203 are threadedly connected, when the longitudinal screw 202 rotates, the longitudinal slider 203 will move linearly along the longitudinal screw 202, thereby driving the longitudinal sliders 203 on both sides to slide back and forth, thereby adjusting the distance between the shoulder pulling strap and the patient's shoulder; the shoulder can be fixed to a suitable position according to factors such as the patient's body shape to ensure the fixation effect and patient comfort.

[0038] The rotation of the transverse motor 205 drives the transverse connecting rod 208 at the front end to rotate. The transverse screws 207 symmetrically arranged on both sides of the transverse connecting rod 208 have the same thread pitch but opposite thread rotation directions, and are respectively threadedly connected to the transverse slider 206. When the transverse connecting rod 208 rotates, the transverse sliders 206 on both sides will make transverse linear motions toward or away from each other, and are slidably connected to the shoulder pulling slider 210 through the transverse sliding groove 209 arranged at the front end of the transverse slider 206. The shoulder pulling slider 210 moves closer to or away from each other laterally under the drive of the transverse slider 206, thereby adjusting the distance between the two limit seats 212, so that it can be adjusted to a suitable position for patients with different body shapes such as different shoulder widths to stabilize and fix the shoulders;

[0039] In this embodiment, the forearm fixing strap 215, the first shoulder strap 216, and the second shoulder strap 217 in the device are all made of elastic straps. This material can provide sufficient tension to fix the patient's shoulders and forearms to ensure the stability of the patient's body during the operation, and can also adapt to the patient's subtle movements to a certain extent, avoiding discomfort to the patient caused by over-tightening, allowing the patient to maintain a relatively comfortable state in the surgical position, and reducing the unconscious displacement caused by discomfort;

[0040] The shoulder pad 103 in the support assembly 1 provides cushioning support for the patient's shoulders, and the hand rest 104 facilitates the patient to place his hands, so that the patient is in a more natural and comfortable posture, further improving the patient's comfort during the operation. The various adjustment mechanisms accurately fix the body position, ensuring the stability of the patient's body during the operation, and helping the operation to proceed smoothly.

[0041] In this embodiment, the shoulder pull assembly 2 is provided with a lateral adjustment mechanism and a longitudinal adjustment mechanism, so that the shoulder pull assembly 2 can be accurately adjusted in both the lateral and longitudinal directions according to the differences in body shapes such as shoulder width and shoulder height of different patients, thereby achieving stable and comfortable fixation of the patient's shoulders, effectively avoiding the problem of unstable fixation caused by the inability of the fixing device to adapt to body shape differences, and providing the surgeon with good surgical field exposure conditions.

[0042] Embodiment 2

[0043] like Figure 1-3As shown in FIG. 6 , the head assembly 3 includes a telescopic mechanism, a lifting mechanism, and a head support 310; a lifting mechanism is provided at the rear end of the telescopic mechanism; and a head support 310 is provided at the upper end of the lifting mechanism;

[0044] The telescopic mechanism includes a head telescopic plate 301, a telescopic screw 302, and a telescopic rocker 303; the telescopic plate is U-shaped, with the front end slidingly connected to the bed body 101, a hole in the middle threadedly connected to the telescopic screw 302, and the top of the rear end fixedly connected to the lifting mechanism; the front end of the screw is rotatably connected to the bed body 101, and the rear end is provided with a telescopic rocker 303;

[0045] The lifting mechanism includes a lifting seat 304, a lifting shaft 305, a lifting connecting rod 306, an adjusting seat 307, a lifting screw 308, a lifting knob 309, and a head frame 311; the bottom of the lifting seat 304 is fixedly connected to the telescopic plate, and the lifting shafts 305 are symmetrically arranged on both sides of the middle; the lifting shaft 305 is symmetrically rotated to connect one end of the crank; the middle part of the crank is rotated to connect to the adjusting seat 307, and the end is rotated to connect to the head frame 311; a hole is opened in the middle of the adjusting seat 307, and a lifting knob 309 is arranged on the side of one side of the adjusting seat 307; a lifting screw 308 is arranged at the front end of the lifting knob 309 to be threadedly connected and penetrate the two supports; the thread pitch of the adjusting seat 307 on both sides is the same, and the thread rotation direction is opposite;

[0046] In this embodiment, the working principle of the head assembly 3 is as follows: when the telescopic rocker 303 is rotated, the telescopic screw 302 rotates accordingly, driving the head telescopic plate 301 to perform a linear telescopic movement forward and backward along the bed body 101. Since the top of the rear end of the telescopic plate is fixedly connected to the lifting mechanism, the lifting mechanism will move forward and backward together with the telescopic plate, so as to adapt to the difference in body length of different patients, adjust the position of the head assembly 3 in the front and rear direction, and ensure that the head support 310 can be in a suitable position to support the patient's head;

[0047] When the lifting knob 309 is turned, the lifting screw 308 rotates, driving the two adjustment seats 307 to make linear movements toward or away from each other, thereby causing the head frame 311 to move upward or downward, driving the head support 310 at the upper end to change its height in the longitudinal direction. The height of the head support 310 can be flexibly adjusted according to factors such as the body shape of different patients and the height requirements of the head when lying on the side, thereby improving the comfort of the patient's head support, avoiding the patient's displacement during the operation due to head discomfort, and ensuring the safety and smooth progress of the operation;

[0048] In this embodiment, the telescopic mechanism in the head assembly 3 can drive the telescopic screw 302 to rotate by rotating the telescopic rocker 303, so that the head telescopic plate 301 can be telescoped forward and backward along the bed 101, and the front and rear position of the head assembly 3 can be adjusted to adapt to the difference in body length of different patients; the lifting mechanism drives the adjustment seat 307 to move by rotating the lifting knob 309, and the lifting and lowering of the head support 310 is realized through the crank transmission, and the height can be flexibly adjusted according to the height requirements of the head of different patients when lying on their side; through the two aspects of adjustment, comfortable and appropriate support can be provided for the heads of different patients, thereby improving the comfort of patients, reducing the risk of displacement caused by head discomfort, and ensuring the safety of surgery.

[0049] In summary, the present invention provides a lateral adjustment mechanism and a longitudinal adjustment mechanism in the shoulder pull assembly 2. Through the synergistic effect of the two, the shoulder pull strap can be flexibly adjusted in the lateral and longitudinal directions according to the patient's specific body characteristics such as height and shoulder width. It ensures that the shoulder pull strap can accurately act on the appropriate position of the patient's shoulder, provides a stable and reliable fixation effect, effectively prevents body displacement caused by poor fixation, and ensures smooth operation.

[0050] At the same time, the telescopic mechanism and the lifting mechanism of the head assembly 3 cooperate with each other, and can accurately adjust the extension length and height of the head support according to the height and body shape of different patients; through adjustment, the patient's head can be in a natural and comfortable position, reducing the discomfort caused by improper head support, reducing the patient's unconscious movement due to discomfort, ensuring the stability of the patient's head position during the operation, and providing favorable conditions for surgical operations.
