Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a surgical fixing bracket for general surgery. Background Art

[0002] General surgery is a department that covers a wide range of surgical diseases, including surgical procedures on many parts of the body. Within the scope of general surgery, hand surgery usually involves surgical treatment of hand trauma, infection, tumors and other diseases. Currently, general surgeons usually use hand fixation braces to fix the patient's hand when performing surgery on the patient to ensure that the operation can be carried out smoothly.

[0003] At present, a Chinese patent discloses a fixed bracket for general surgery (authorization announcement number CN210408927U). During the operation, the patient's hand is placed on the top wall of the pad, and the five fingers are placed on the centripetal top walls of the five groups of limit rods respectively. The five fingers are bound to the centripetal top walls of the limit rods by using medical bandages, and the opening angle of the patient's five fingers is adjusted by sliding the sliding member. Among them, the fixing of the sliding member is to tighten the first bolt so that the first bolt is tightly against the top wall of the pad to complete the limitation of the sliding member; the limit member moves centripetally along the screw rod body of the first bolt and the second bolt through the slide groove, so as to facilitate the stretching adjustment of the limit rod according to the patient's finger length, and by tightening the second bolt, the second bolt cooperates with the pinch block to clamp and fix the limit rod.

[0004] According to the above reference cases, the above device uses five sets of limiters to lock the spread angles of the patient's five fingers. Since the specifications of the limiters are fixed and the patient's index finger, middle finger and ring finger need to be fixed on both sides at the same time, the five sets of limiters are difficult to lock the patient's five fingers at the corresponding angles, and it is difficult to ensure that each finger of the patient is effectively locked, and the fixation effect is poor. Summary of the invention

[0005] Based on this, it is necessary to provide a general surgical fixation bracket to address the problem that the existing general surgical finger fixation bracket is difficult to effectively fix each finger and the fixation effect is poor.

[0006] A surgical fixation bracket for general surgery comprises a slide groove pad, the inner side of which is slidably connected to sliding members evenly distributed, the surface of which is slidably connected to a limit frame, and the surface of which is mounted with an adjustable locking mechanism in contact with the slide groove pad.

[0007] Furthermore, the adjustable locking mechanism includes a sliding limit assembly and a rotating shaft, the sliding limit assembly is slidably connected to the surface of the limit frame, the rotating shaft is fixedly connected to the inner side of the limit frame, and the surfaces of the sliding limit assembly and the rotating shaft are both rotatably connected with two guide strips, and the four guide strips together form a rhombus.

[0008] In one of the embodiments, medical personnel can adjust the size of the diamond composed of four guide strips by simply pushing the sliding limit assembly in the direction of the rotating shaft, so that it can effectively fit in the finger gaps of corresponding opening and closing degrees. Compared with the existing fixed finger fixing bracket, this can effectively meet the locking requirements of patients' fingers with different finger gap sizes and corresponding opening and closing degrees, ensuring that the patient's fingers are effectively locked, thereby solving the problem that the existing finger fixing brackets for general surgery are difficult to effectively fix each finger and the fixing effect is poor.

[0009] Furthermore, the adjustable locking mechanism also includes a rubber sheath, and the four guide strips are all fixedly connected to the inner side of the rubber sheath.

[0010] In one embodiment, the rubber sheath can reduce the probability of the patient's fingers being crushed by the guide strip.

[0011] Furthermore, the horizontal cross-section of the rubber sheath is a rhombus, the vertical cross-section of the rubber sheath is an inverted L-shape, and the corners of the rubber sheath are rounded.

[0012] In one of the embodiments, an inverted L-shaped design is adopted, which can effectively prevent the patient's fingers from lifting up, effectively reduce the probability of the patient's hand muscle movement, and further improve the locking effect on the patient's fingers.

[0013] Furthermore, two adjacent guide bars are arranged in a staggered manner, and the corners of the guide bars are rounded.

[0014] In one of the embodiments, this can increase the telescopic range of the diamond formed by the guide strips to meet the fixation requirements of patients with different finger opening and closing degrees.

[0015] Furthermore, the sliding limit assembly includes an I-shaped sleeve slidably connected to the surface of the limit frame, wherein one end of the two guide strips are rotatably connected to the I-shaped sleeve, the top of the I-shaped sleeve is threadedly connected with a threaded column, the bottom of the threaded column passes through the I-shaped sleeve and contacts with the slide groove pad, the inside of the I-shaped sleeve is slidably connected with a friction block in contact with the limit frame, and the surface of the threaded column is fixedly connected with a push rod in contact with the friction block.

[0016] In one of the embodiments, medical staff only need to slightly rotate the threaded column to complete the fixation and unlocking requirements of the patient's fingers. Compared with the existing fixed finger fixation bracket, this effectively improves the operating efficiency of medical staff.

[0017] Furthermore, the cross-sectional shape of the end of the push rod facing away from the threaded column is an arc shape.

[0018] In one embodiment, this can reduce the probability that the push rod will get the friction block stuck inside the I-shaped sliding sleeve, so as to ensure that the push rod can drive the friction block to move easily.

[0019] Furthermore, the number of the friction blocks and the push rods are both two, the two push rods are symmetrically distributed on both sides of the axis of the threaded column, and the two friction blocks are staggeredly distributed on both sides of the axis of the threaded column.

[0020] In one of the embodiments, this can increase the friction area of ​​the I-shaped sliding sleeve against the limiting frame, so as to improve the locking effect of the I-shaped sliding sleeve.

[0021] Furthermore, both ends of the I-shaped sliding sleeve are provided with rectangular guide openings, and the friction block is slidably connected to the inside of the rectangular guide openings.

[0022] In one embodiment, this can limit the friction block to only slide along the rectangular guide opening to reduce the probability of the friction block being stuck.

[0023] Furthermore, the friction block includes two hard friction plates, a rubber plate is bonded between the two hard friction plates, the hard friction plate and the rubber plate are both slidably connected to the inside of the rectangular guide opening, and the two hard friction plates are in contact with the limit frame and the push rod respectively.

[0024] In one embodiment, this enables the friction block to have enough expansion and contraction space to ensure that when the threaded column and the slide groove pad are tightly abutted together, the friction block is also pressed against the inner side of the limit frame.

[0025] Furthermore, a knob is fixedly connected to the top of the threaded column, and the corners of the knob are rounded.

[0026] In one embodiment, this can reduce the burden on medical personnel in adjusting the threaded column, further improving the adjustment efficiency of medical personnel.

[0027] With the above-mentioned general surgery fixation bracket, medical staff can adjust the size of the rhombus formed by the four guide strips by simply pushing the sliding limit assembly in the direction of the rotating shaft, so that it can effectively fit in the finger gaps of the corresponding opening and closing degrees. Compared with the existing fixed finger fixation bracket, this can effectively meet the locking requirements of the patient's fingers with different finger gap sizes and corresponding opening and closing degrees, ensuring that the patient's fingers are effectively locked, thereby solving the problem that the existing general surgery finger fixation bracket is difficult to effectively fix each finger and has a poor fixing effect;

[0028] At the same time, the diamond-shaped corners of the guide strip can effectively fit the patient's finger bones and block the patient's knuckles, which can prevent the patient from pulling his hand back, further improving the locking effect of the patient's fingers. The rubber sheath can not only reduce the probability of the patient's fingers being crushed by the guide strip, but also adopts an inverted L-shaped design, which can effectively prevent the patient's fingers from lifting up, effectively reducing the probability of the patient's hand muscle movement, and further improving the locking effect of the patient's fingers.

The term "and / or" used in the specification of the present invention includes any and all combinations of one or more related listed items.

[0045] Combine the following Figure 1 - Figure 8The present invention describes a surgical fixation bracket for general surgery.

[0046] In one embodiment, a surgical fixation bracket for general surgery includes a slide groove pad 100, the inner side of the slide groove pad 100 is slidably connected to a uniformly distributed sliding member 200, the surface of the sliding member 200 is slidably connected to a limit frame 300, and the surface of the limit frame 300 is installed with an adjustable locking mechanism 400 that contacts the slide groove pad 100.

[0047] The slide groove pad 100 includes an upper pad and a lower pad, the top of the lower pad is fixedly connected with a threaded disk threadedly connected to the upper pad, the axis lines of the upper pad, the lower pad and the threaded disk are all coincident, a connected annular groove is provided between the upper pad and the lower pad, the vertical cross-section shape of the two annular grooves combined together is a side convex shape, the sliding member 200 includes a slider slidably connected between the two annular grooves, the top of the slider is fixedly connected with an I-shaped column, and the limit frame 300 is slidably connected to the concave part of the I-shaped column;

[0048] Before use, the medical staff will first insert the slider into the ring groove of the upper pad according to the needs. When all the sliders are installed in place, the medical staff will then connect the threaded disk on the lower pad with the upper pad thread until the upper pad and the lower pad fit tightly together. At this time, the upper and lower ring grooves cooperate to lock the slider firmly, and then the medical staff can use the finger to fix the bracket normally.

[0049] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the adjustable locking mechanism 400 includes a sliding limit assembly 410 and a rotating shaft 420. The sliding limit assembly 410 is slidably connected to the surface of the limit frame 300, and the rotating shaft 420 is fixedly connected to the inner side of the limit frame 300. The surfaces of the sliding limit assembly 410 and the rotating shaft 420 are both rotatably connected with two guide bars 430. The four guide bars 430 together form a rhombus. Medical staff only need to push the sliding limit assembly 410 in the direction of the rotating shaft 420 to adjust the size of the rhombus formed by the four guide bars 430 so that it can effectively fit in the finger gaps of the corresponding opening and closing degrees. Compared with the existing fixed finger fixing bracket, this can effectively meet the locking requirements for different finger gap sizes and corresponding opening and closing degrees of the patient's fingers, ensure that the patient's fingers are effectively locked, and thus solve the problem that the existing finger fixing bracket for general surgery is difficult to effectively fix each finger and the fixing effect is poor.

[0050] The adjustable locking mechanism 400 also includes a rubber sheath 440, and the four guide strips 430 are fixedly connected to the inner side of the rubber sheath 440. The rubber sheath 440 can reduce the probability of the patient's fingers being crushed by the guide strips 430; the horizontal cross-sectional shape of the rubber sheath 440 is a rhombus, and the vertical cross-sectional shape of the rubber sheath 440 is an inverted L-shape. The corners of the rubber sheath 440 are rounded, and the inverted L-shaped design is adopted, which can effectively prevent the patient's fingers from lifting up, effectively reduce the probability of the patient's hand muscle movement, and further improve the locking effect of the patient's fingers; two adjacent guide strips 430 are staggered, and the corners of the guide strips 430 are rounded, which can increase the expansion and contraction range of the rhombus formed by the guide strips 430 to meet the fixation requirements of patients with different finger opening and closing degrees.

[0051] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the sliding limit assembly 410 includes an I-shaped sleeve 411 slidably connected to the surface of the limit frame 300, wherein one end of the two guide strips 430 are rotatably connected to the I-shaped sleeve 411, the top of the I-shaped sleeve 411 is threadedly connected with a threaded column 412, the bottom of the threaded column 412 passes through the I-shaped sleeve 411 and contacts with the slide groove pad 100, the inside of the I-shaped sleeve 411 is slidably connected with a friction block 413 in contact with the limit frame 300, and the surface of the threaded column 412 is fixedly connected with a push rod 414 in contact with the friction block 413. Medical staff only need to slightly rotate the threaded column 412 to complete the fixing and unlocking requirements of the patient's fingers. Compared with the existing fixed finger fixing bracket, this effectively improves the operating efficiency of medical staff.

[0052] The cross-sectional shape of the end of the push rod 414 facing away from the threaded column 412 is an arc shape, which can reduce the probability that the push rod 414 will get the friction block 413 stuck inside the I-shaped sliding sleeve 411. To ensure that the push rod 414 can drive the friction block 413 to move easily; the number of friction blocks 413 and push rods 414 are both two, and the two push rods 414 are symmetrically distributed on both sides of the axis of the threaded column 412, and the two friction blocks 413 are staggered on both sides of the axis of the threaded column 412, which can increase the friction area of ​​the I-shaped sliding sleeve 411 against the limit frame 300, so as to improve the locking effect of the I-shaped sliding sleeve 411; rectangular guide openings 415 are provided at both ends of the I-shaped sliding sleeve 411, and the friction block 413 is slidably connected to the inside of the rectangular guide opening 415, which can limit the friction block 413 to only slide along the rectangular guide opening 415, so as to reduce the probability of the friction block 413 being stuck; the friction block 413 includes two The hard friction sheet 4131 is provided with a rubber sheet 4132 bonded between the two hard friction sheets 4131. The hard friction sheet 4131 and the rubber sheet 4132 are both slidably connected to the inside of the rectangular guide opening 415. The two hard friction sheets 4131 are in contact with the limit frame 300 and the push rod 414 respectively, which enables the friction block 413 to have enough expansion and contraction space to ensure that when the threaded column 412 and the slide groove pad 100 are tightly abutted together, the friction block 413 is also pressed against the inner side of the limit frame 300; the top of the threaded column 412 is fixedly connected with a knob 416, and the corners of the knob 416 are rounded, which can reduce the burden of medical staff in adjusting the threaded column 412, and further improve the adjustment efficiency of medical staff;

[0053] When the medical staff adjusts the guide strip 430 to the right position, the medical staff only needs to rotate the knob 416 in the corresponding direction, and the knob 416 drives the threaded column 412 to spirally move downward, and at the same time, the threaded column 412 drives the push rod 414 to rotate. When the threaded column 412 abuts against the upper pad, the threaded column 412 pushes up the I-shaped sliding sleeve 411, and the I-shaped sliding sleeve 411 drives the limit frame 300 to abut tightly against the I-shaped column. At this time, the threaded column 412, the I-shaped sliding sleeve 411, the limit frame 300, the sliding member 200 and the slide groove pad 100 restrain each other, and the adjustable locking mechanism 400 is firmly locked on the slide groove pad 100, which can not only effectively lock the patient's fingers, but also the medical staff can complete the locking and unlocking operations with only one step of operation, which can also improve the operating efficiency of the medical staff;

[0054] When the threaded column 412 rotates, the threaded column 412 synchronously drives the push rod 414 to rotate, and the push rod 414 pushes the friction block 413 along the outer rotation of the rectangular guide opening 415. When the threaded column 412 and the slide groove pad 100 are tightly abutted together, the friction block 413 is also pressed against the inner side of the limit frame 300, which can increase the friction between the I-shaped sliding sleeve 411 and the limit frame 300, effectively reducing the probability of the I-shaped sliding sleeve 411 loosening, thereby ensuring that the guide bar 430 can maintain its original state.

[0055] Working principle: When the medical staff needs to lock the opening and closing of two adjacent fingers, the medical staff first moves the limit frame 300 together with the adjustable locking mechanism 400 to the gap between the fingers, and fits the end of the rubber sheath 440 close to the rotating shaft 420 with the deepest part of the finger gap. Then the medical staff pushes the sliding limit assembly 410 in the direction of the rotating shaft 420. At this time, the sliding limit assembly 410 drives the two guide bars 430 connected thereto to synchronously approach the rotating shaft 420, and because the other two guide bars 430 are rotatably connected to the surface of the rotating shaft 420, they are not in contact with the sliding limit assembly 410 and The hinges of the two guide bars 430 connected to the rotating shaft 420 expand synchronously, so that the angle between the two guide bars 430 connected to the rotating shaft 420 expands synchronously and pushes against two adjacent fingers respectively until the opening and closing degree of the two fingers is adjusted to a preset angle. At this time, the medical staff can lock the sliding limit assembly 410 to effectively lock the opening and closing degree of the two adjacent fingers. This can effectively meet the locking requirements for the opening and closing degree of the patient's fingers and ensure that the patient's fingers are effectively locked. When the medical staff has fixed all five fingers, the patient's fingers are firmly locked on the top of the slide groove pad 100.

[0056] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
