Description

Technical Field

[0001] The invention relates to the field of pelvic surgery medical instruments, and in particular to a pelvic repositioning device. Background Art

[0002] In minimally invasive pelvic surgery, the two ends of the reduction frame and the two sides of the operating table are usually fixed, and then screws are inserted into the pelvis for fixation. The screws and the reduction frame are fixed, so that the reduction frame and the patient's pelvis are fixed, and the joints are pulled to complete the reduction. Depending on the extent of the pelvic injury, the patient can choose to lie on his back or side during surgery.

[0003] To ensure the stability of the reduction frame, the reduction frame usually adopts a fixed bracket, and the height is not adjustable. If the height of the reduction frame is appropriate when the patient lies on his back, the pelvis of the patient will be closer to the reduction frame when the patient lies on his side, which makes it inconvenient to insert the screw into the pelvis.

[0004] In addition, the reduction frame includes arch frames fixed on both sides of the operating table and connecting rods between the arch frames. When the pelvis needs to be fixed with screws in the horizontal direction, the connecting rods are located above the torso, and the directions in which the connecting rods and the screws are inserted into the pelvis are nearly parallel, resulting in a poor force-bearing structure. Therefore, the screws are usually fixed to the arch frames on both sides. However, when the patient lies on his side, the front and back sides of the patient's torso are farther away from the two sides of the operating table than when lying on his back. Therefore, the sides of the patient's torso are farther away from the two ends of the reduction frame, resulting in the screws and the fixed ends of the reduction frame being farther away from the patient's torso, thereby affecting the stability of the fixation effect.

[0005] Therefore, there is a need for a pelvic reduction device that is suitable for the side-lying position during pelvic surgery and can stabilize the patient's body when screws are used in the horizontal direction. Summary of the invention

[0006] The present invention is intended to provide a pelvic reduction device suitable for a side-lying position in pelvic surgery, which can stabilize the patient's body when a screw is used in a horizontal direction.

[0007] To achieve the above object, the present invention adopts the following technical scheme: a pelvic reduction device, comprising an operating table and a reduction frame, the operating table comprising an upper body bed, a strip-shaped side-lying groove is provided on the upper side of the upper body bed, the side-lying groove is used to accommodate the body of the patient facing downward when lying on his side, the reduction frame comprises two arch frames, the two arch frame brackets are provided with connecting rods, and the arch feet of the arch frames are detachably connected to the upper surface of the upper body bed;

[0008] When the patient lies on his side, the arch frame spans over the side-lying groove, and the length direction of the connecting rod is parallel to the length direction of the upper body bed; when the patient lies on his back, the two arch frames are respectively installed on both sides of the upper body bed, and the length direction of the connecting rod is perpendicular to the length direction of the upper body bed.

[0009] The beneficial effects of this program are:

[0010] 1. When the side-lying position is required, the patient's body facing downward is accommodated in the side-lying groove. The depth of the side-lying groove is set according to needs so that the distance between the upper side of the patient's body and the reduction frame is consistent with the distance between the patient's body and the reduction frame when lying on the back, thereby ensuring that the distance between the patient and the reduction frame is the optimal operating distance in both the supine and side-lying positions.

[0011] 2. When the patient lies on his back, the two arch frames are respectively installed on both sides of the upper body bed to facilitate the fixing of the connecting rods between the screws and the arch frames, thereby fixing the reduction frame and the patient's pelvis.

[0012] 3. To adapt to the patient's side-lying posture, this solution designs the two ends of the reduction frame into arch frames. When the patient needs to lie on his side, the reduction frame is rotated 90° so that the arch frame spans the side-lying groove. The size of the arch frame is designed according to the actual situation, and it can accommodate the patient's body and reserve space for surgical operations. Since the patient changes from lying on his back to lying on his side, the width of the horizontal projection of the patient's body is reduced, so the span of the arch ring of the arch frame is smaller than the span of the connecting rod between the two arch frames;

[0013] Compared with the prior art, when it is necessary to fix the pelvis with screws in the horizontal direction, the connecting rod near the arch foot of the arch frame is made closer to the patient's side, and the direction in which the connecting rod and the screw are inserted into the pelvis is close to vertical, and the force-bearing structure is good, so as to facilitate the fixation of the screws and the connecting rod, thereby ensuring that the screws can stabilize the patient's body.

[0014] Furthermore, the upper body bed also includes a filling part, and when the patient lies on his back, the filling part fills the upper surface of the side-lying groove.

[0015] Furthermore, the bottom width of the side-sleeping groove is smaller than the top width. The side-sleeping groove includes a waist and back area and a thigh area. The thigh area is provided with a restraint belt, which is used to cooperate with the thigh area to bind the patient's lower thigh. A clamping unit is respectively provided on both sides above the waist and back area. The two clamping units are used to clamp the patient's waist and back, and the clamping units are detachably connected to the upper body bed.

[0016] Furthermore, the operating bed also includes a lower body bed, the thigh area runs through the upper body bed close to the lower body bed, the side lying groove also includes a shoulder area, the depth of the shoulder area is greater than the thigh area; two arm grooves are symmetrically arranged on both sides of the shoulder area, the two arm grooves are perpendicular to and connected to the shoulder area, and the arm grooves run through the side of the upper body bed.

[0017] Furthermore, two arm slots are symmetrically arranged on both sides of the shoulder area. Both arm slots are perpendicular to and connected to the shoulder area, and both arm slots run through the side of the upper body bed.

[0018] Furthermore, an extension portion is provided in the arm slot, and the extension portion is used to fill the upper surface of the arm slot. The extension portion is rotatably connected to the arm slot at one end close to the outer side of the upper body bed. After the extension portion is rotated and flipped, the upper surface of the extension portion is flush with the bottom of the arm slot and spliced.

[0019] Furthermore, before the extension portion rotates, a side of the extension portion close to the shoulder region is recessed relative to a side wall of the shoulder region.

[0020] Furthermore, the lower body bed includes a support plate, to which a plurality of limit columns are detachably connected. The plurality of limit columns include a sole column, an ankle column and a hindfoot column. The sole column, the ankle column and the hindfoot column are respectively used to contact the sole, the instep and the Achilles tendon of the lower foot when the patient lies on his side, and the ankle column is also used to contact the front side of the ankle of the upper foot.

[0021] Furthermore, the support plate is provided with a plurality of connection holes, which are used for threaded connection with the limiting columns. The plurality of connection holes are divided into a plurality of rows, and the connection holes in each row are arranged in an arc, with the inner side of the arc facing the upper body bed.

[0022] Furthermore, adjustable bed legs are provided under the support plate, and the adjustable bed legs are divided into two levels. In the first level, the support plate is flush with the bottom of the thigh area of ​​the side lying slot; in the second level, the support plate is flush with the upper body bed surface.

[0023] Furthermore, the clamping unit includes a clamping cylinder, which is bolted to the upper body bed, and a clamping plate is provided at the end of the output shaft of the clamping cylinder, and the two clamping plates are used to clamp the patient's waist and back.

[0024] This solution also has the following effects:

[0025] 1. When the patient needs to lie on his side, surgery is usually performed on one side of the pelvis, so that side is facing upward, requiring the patient to lie on his side. In this solution, a restraint belt is passed between the patient's thighs, which will not affect the operating space near the surgical site, and can also tie and fix the patient's lower thigh, thereby limiting the displacement of the patient's lower body and performing preliminary fixation of the patient's body. Since only the lower body is fixed, the movement tendency of the upper body to tilt and rotate around the lower body is not restricted, so additional fixation is required.

[0026] 2. Although the shape of the pelvis makes it difficult to fix the patient, the back and lower abdomen above the pelvis are relatively flat. In this solution, the upper torso of the patient can be fixed using a clamping unit, thereby limiting the inclination of the upper torso and rotating around the lower torso, thereby supplementing the fixation of the patient's torso. The two fixation methods complement each other, thereby stabilizing the patient's torso in the side-lying position, preventing the torso from shaking during surgery, improving the position accuracy of the traction joint, and ensuring the efficiency and effectiveness of pelvic surgery.

[0027] 3. When the filling part fills the side-lying groove, the operating table can be used for supine lying; when the filling part is removed, the operating table can be used for side-lying; this solution can adapt to different surgical scenes without the need to replace different operating tables, thereby saving surgical preparation time.

[0028] 4. The support plate is used to support the patient's feet. The limit column limits the patient's legs by limiting the feet, thereby preventing the patient from tilting or turning the body during the operation.

[0029] Specifically, when lying on the side, the patient's feet are placed on the support board, wherein the lower foot is placed on the support board and leans back, the sole column, ankle column and hindfoot column are respectively in contact with the sole, instep and Achilles tendon of the lower foot of the patient when lying on the side, the upper foot is placed upright on the support board and leans forward, the ankle column is in contact with the outer side of the ankle of the upper foot, at this time, the two feet cross-clamp the ankle column, based on the ligament tension of the human body, the ankle column is automatically locked and clamped, and the tilting and turning of the body can be restricted, thereby achieving the purpose of limiting the position of the patient's feet;

[0030] Among them, the sole column and the rear foot column assist in limiting the lower foot. The rear foot column is used to prevent the calf from bending, thereby preventing the lower foot from moving backward to release the self-locking state; the sole column is used to support the sole of the foot, thereby assisting in positioning the lower foot.

[0031] In pelvic surgery, one of the feet usually needs to be put into a specific posture to assist in pelvic joint reduction, such as knee flexion, thigh swinging back, etc. When the patient lies on his side, the upper leg is usually put into a specific posture. Therefore, this solution mainly limits the lower foot to facilitate medical staff to pick up the upper foot and put it into a specific posture; in the case where the upper thigh needs to be swung back, when fixing the lower foot, the lower leg is swung forward in advance and then fixed, so that when the rear thigh swings back, there can be a sufficient angle between it and the front thigh, thereby ensuring that the joint reduction effect in the specific posture is more significant.

[0032] Since the patient's legs rotate roughly around the thigh root in an arc shape regardless of whether they are moving forward or backward, in this solution, the line shape of each row of connecting holes is set to an arc shape to facilitate adjusting the position of the limit column according to the patient's body shape, proportions, and joint ligaments.

[0033] 5. The depth of the shoulder area is greater than that of the thigh area, that is, the entire side-lying groove is close to the inclined setting; the depth of the shoulder area is shallow, so that the patient can place the head on the upper surface of the operating table, making the patient more comfortable;

[0034] 6. In addition, the depth of the shoulder area is greater than that of the thigh area, which prevents the patient's body from sliding upward (i.e., sliding toward the shoulder area), thereby ensuring that after the patient's feet are self-locked on the ankle column, they will not slide upward and contact the self-locking state.

[0035] 7. Set up the arm slot. If you need to lie on your left side, turn over the extension part in the left arm slot so that the upper surface of the extension part is flush with the arm slot and connected, and place the left arm on the arm slot and the extension part to prevent long-term side lying from pressing on the lower arm and affecting the blood supply function.

[0036] The side of the extension portion close to the shoulder region is recessed relative to the side wall of the shoulder region, so as to facilitate the arrangement of a handle on the extension portion while avoiding interference between the handle and the patient's body and the filling portion.

[0046] Example

[0047] The embodiment is basically as follows Figure 1-Figure 6 As shown: pelvic reduction equipment, including an operating table and a reduction frame, such as Figure 1As shown, the operating bed includes an upper body bed 1 and a lower body bed, the upper side of the upper body bed 1 is provided with a strip-shaped side-lying groove 2 and two strip-shaped through holes 13 vertically penetrating the upper and lower surfaces of the upper body bed 1, the resetting frame includes two arch frames, each of which includes an inner arch ring 61 and an outer arch ring 62 equidistant from each other, the arch feet of the inner arch ring 61 and the outer arch ring 62 are both vertically provided with straight extension sections, the length of the straight extension section of the inner arch ring 61 is greater than the straight extension section of the outer arch ring 62, and a connecting block 64 is welded at the lower end of the straight extension section of the inner arch ring 61, and the connecting block 64 is used to connect with the upper surface of the upper body bed 1 Bolt connection, a plurality of bolt holes are opened on the upper surface of the upper body bed 1, so the bolt connection position of the connecting block 64 and the upper body bed 1 is adjustable; a plurality of radial rods 63 are welded between the inner arch ring 61 and the outer arch ring 62, and a plurality of horizontal connecting rods 65 are welded between the outer arch rings 62 of the two arch frames, and the connecting rods 65 are used to be fixedly connected with the exposed part of the screw inserted into the patient's pelvis; the distance between the arch feet of the inner arch ring 61 is greater than the width of the lateral lying groove 2 and less than the length of the connecting rod 65; a clamping unit is usually arranged on the connecting rod 65, and the clamping unit clamps the screw to achieve fixation.

[0048] Compared with only one arch ring, the present solution has two arch rings. The inner arch ring 61 is used to connect with the upper body bed 1, so the span of the inner arch ring 61 is smaller to maintain the stability of the overall structure; while the outer arch ring 62 has a larger span and is used to connect with the connecting rod 65, ensuring that there is operating space between the connecting rod 65 and the patient's body to facilitate fixing the screws.

[0049] When the patient lies on his side, the arch frame spans over the side-lying groove 2, the arch feet of the inner arch ring 61 of the arch frame are arranged on both sides of the side-lying groove 2, and the length direction of the connecting rod 65 is parallel to the length direction of the upper body bed 1; when the patient lies on his back, the two arch frames are respectively installed on both sides of the upper body bed 1, and the length direction of the connecting rod 65 is perpendicular to the length direction of the upper body bed 1.

[0050] like Figure 2 As shown, the upper body bed 1 includes a headrest 11 and a filling part 12. The filling part 12 matches the shape of the side lying groove 2. The filling part 12 is used to fill the upper surface of the side lying groove 2. After the side lying groove 2 is filled, the patient can lie on his back. In this solution, the upper side and the lower side of the patient refer to the direction when the patient lies on his side, the front side of the patient refers to the side where the patient's face faces, and vice versa, the back side. The fact that structures irrelevant to the core content, such as guardrails, are omitted in the present invention does not mean that these structures are not present in the actual product.

[0051] like Figure 7 As shown, the side-lying groove 2 is used to accommodate the downward side of the patient's body when lying on the side, the bottom width of the side-lying groove 2 is smaller than the top width, the side wall is inclined, and the side-lying groove 2 is inclined in the length direction. The side-lying groove 2 includes a shoulder area 21, a waist and back area 22, and a thigh area 23 with depths from shallow to deep.

[0052] The shoulder area 21 is arranged at one end of the side lying groove 2 close to the headrest 11, the thigh area 23 runs through the upper body bed 1 close to the lower body bed, and two strip-shaped perforations 13 are symmetrically arranged on both sides of the thigh area 23;

[0053] The thigh area 23 is provided with a restraint belt (not shown in the figure), which is used to pass between the patient's legs, the two strip-shaped perforations 13 and the lower side of the upper body bed 1, and cooperate with the thigh area 23 to bind the patient's lower thigh. The restraint belt is an adjustable tightness medical restraint belt. The restraint belt is a prior art and will not be described in detail.

[0054] like Figure 1 As shown, a clamping unit is provided on both sides above the waist and back area 22, and the two clamping units are used to clamp the patient's waist and back, and the clamping units are detachably connected to the upper body bed 1. The clamping unit includes a clamping cylinder 14, and the clamping cylinder 14 is bolted to the upper body bed 1, and the output shaft end of the clamping cylinder 14 is bolted to a clamping plate 15, and the clamping plates 15 of the two clamping units are used to clamp the patient's waist and back.

[0055] like Figure 1 , Figure 2 As shown, the operating bed has two arm slots 31, which are symmetrically arranged on both sides of the shoulder area 21, and the two arm slots 31 are perpendicular to and connected to the shoulder area 21. The arm slots 31 all pass through the side of the upper body bed 1, and an extension portion 32 is provided in the arm slot 31. The extension portion 32 is used to fill the upper surface of the arm slot 31, and a horizontal rotating shaft 35 is welded on the lower side of the extension portion 32 close to the outer end of the upper body bed 1. Two ear plates 34 are integrally formed on both sides of the upper body bed 1, and the rotating shaft 35 passes through the two ear plates 34 at the same time and is rotatably connected to the two ear plates 34, so that the extension portion 32 and the arm slot 31 are rotatably connected; as shown in FIG. Figure 1 , Figure 2 As shown, before the extension part 32 rotates, the extension part 32 is accommodated in the arm groove 31 and fills the upper surface and the outer side (the side away from the shoulder area 21) of the arm groove 31, and the inner side (the side close to the shoulder area 21) of the extension part 32 is recessed relative to the side wall of the shoulder area 21 to form a temporary groove, and a rectangular handle 33 is welded on this side of the extension part 32; Figure 1 As shown, after the extension part 32 is rotated and flipped, the upper surface of the extension part 32 is flush with and spliced ​​with the bottom of the arm slot 31. Since the end of the extension part 32 contacts the side of the upper body bed 1 after the extension part 32 is flipped, the extension part 32 can only be flipped 180° at most and then cannot continue to rotate.

[0056] A longitudinal limiting portion (not shown in the figure) is provided on both sides of the filling portion 12. The longitudinal limiting portion is used to be inserted vertically into the temporary groove, so as to limit the longitudinal position of the filling portion 12 through the temporary groove; after the longitudinal limiting portion is inserted into the temporary groove, it is pressed on the rectangular handle 33 of the extension portion 32. When the patient lies on the filling portion 12, the longitudinal limiting portion of the filling portion 12 applies vertical pressure to the rectangular handle 33, thereby limiting the rotation of the extension portion 32, increasing the stability of the structure, and preventing the operating bed from shaking during the operation. The lower body bed includes a support plate 40, on which a plurality of connecting holes 41 and a plurality of limiting columns are provided. The connecting holes 41 are used for threaded connection with the limiting columns. For ease of display, Figure 1-Figure 3 The connection holes 41 and the limiting columns are omitted, and the arrangement of the connection holes 41 is as follows Figure 4 As shown, the plurality of connection holes 41 are divided into a plurality of rows, and the connection holes 41 in each row are arranged in an arc, with the inner side of the arc facing the upper body bed 1; Figure 5 As shown, the plurality of limiting posts include a sole post 42, an ankle post 43 and a rear post 44. The sole post 42, the ankle post 43 and the rear post 44 are respectively used to contact the sole, the instep and the Achilles tendon of the lower foot 51 when the patient lies on his side. The ankle post 43 is also used to contact the front side of the ankle of the upper foot 52. Figure 6 As shown, the sole column 42, the ankle column 43 and the rear column 44 have the same structure, and all include a limit column body 45, the circumferential surface of the limit column body 45 is provided with a flexible material such as sponge or foam, and the lower side of the limit column body 45 is integrally formed with a threaded connection portion 46 for threaded connection with the connection hole 41. The same limit column can be prepared in 2-3 sizes so that it can be replaced according to the thickness of the patient's legs. In addition, a limit column specifically for the supine position can be designed according to the supine position to prevent the patient's feet in the supine position from being moved. This will not be expanded here.

[0057] The support plate 40 is bolted to an adjustable bed leg, and the adjustable bed leg includes an upper table leg 47 and a lower table leg 48 connected by bolts. By changing the position of the bolt connection, the height of the overlapping portion of the upper table leg 47 and the lower table leg 48 can be changed, thereby changing the overall height of the adjustable bed leg; the adjustable bed leg is divided into two levels. In the first level, the support plate 40 is flush with the bottom of the thigh area 23 of the side lying groove 2; in the second level, the support plate 40 is flush with the upper surface of the upper body bed 1.

[0058] The pelvic reduction device is used as follows:

[0059] 1. When the patient needs to lie on his side, the patient's body facing downward is accommodated in the side-lying groove 2. If the patient needs to lie on the left side, the extension part 32 in the left arm groove 31 is turned over to make the upper surface of the extension part flush with the arm groove 31 and spliced ​​together, and the left arm is placed on the arm groove 31 and the extension part to prevent the lower arm from being pressed down and affecting the blood supply function when lying on the side for a long time;

[0060] Use a restraint belt to pass between the patient's thighs, and use a clamping unit to clamp the patient's lower abdomen and back; the length direction of the connecting rod 65 of the reset frame is parallel to the length direction of the upper body bed 1;

[0061] The adjustable bed legs are adjusted to the first gear state, and the patient's feet are placed on the support board 40, wherein the lower foot 51 is placed sideways on the support board 40 and leans backward, and the sole column 42, the ankle column 43 and the rear foot column 44 are respectively in contact with the sole, the instep and the Achilles tendon of the lower foot 51 of the patient when the patient is lying on his side, and the upper foot 52 is placed upright on the support board 40 and leans forward, and the ankle column 43 is in contact with the outer side of the ankle (away from the side of the human body's symmetry axis) of the upper foot 52. At this time, the two feet cross-clamp the ankle column 43, which is automatically locked and clamped based on the ligament tension of the human body, and can also limit the tilting and turning of the body, thereby achieving the purpose of limiting the patient's feet;

[0062] 2. When a supine position is required, flip the extension part 32 so that the extension part 32 is accommodated in the arm groove 31, and the elastic band still remains in a loop state. Place a part of the elastic band in the side-lying groove 2, and the remaining part of the elastic band passes through the strip perforation 13 and is located under the upper body bed 1. Use the filling part 12 to fill the side-lying groove 2. The filling part 12 presses the elastic band. At this time, the handle 33 of the extension part 32 will not interfere with the filling part 12. The length direction of the connecting rod 65 of the reset frame is perpendicular to the length direction of the upper body bed 1. The adjustable bed legs are adjusted to the second gear state, and the patient's feet are placed on the support plate 40.

[0063] When the filling part 12 needs to be removed, the elastic band under the upper body bed 1 is pulled downward, and the elastic band in the side-lying groove 2 is straightened, thereby driving one end of the filling part 12 to move upward, so that the medical staff can lift the filling part 12.

[0064] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
