[0029] A lifting mechanism 600 is provided on the tail clamping mechanism 300 to adjust the height of the tail clamping mechanism 300 in the direction perpendicular to the support plate 100.

[0030] The intervention surgery catheter fixing frame of the present application can stably fix the intervention catheter 700 in the process of surgery treatment by setting the intervention catheter 700 on the support plate 100 and fixing the catheter handle head and tail by the head clamping mechanism 200 and the tail clamping mechanism 300, thereby avoiding the long-time holding of medical staff; the support height of the tail clamping mechanism 300 can be adjusted by setting the lifting mechanism 600 on the tail clamping mechanism 300, so as to adapt to the taper structure design of the outer diameter of the catheter handle 720 from the catheter handle head 721 to the catheter handle tail 722, so that the catheter handle head 721 and the catheter handle tail 722 are on the same horizontal plane; the intervention catheter can be fixed on the fixing frame by the present application, so as to avoid the shaking of the intervention catheter affecting the diagnosis and treatment process, ensure the safety and effectiveness of surgery and the stability of auxiliary imaging image, and be compatible with intervention catheters of different radial sizes and axial lengths, thereby having strong universality, not affecting the later operation of medical staff, and meeting the clinical needs.

[0031] For example, in the intervention surgery catheter fixing frame provided by one embodiment, as shown in Figures 2-3 The head clamping mechanism 200 comprises:

[0032] The base 210 is vertically arranged on the surface of the support plate 100;

[0033] The clamping groove 220 is connected with the base 210 and used for placing the catheter handle head 721, the clamping groove 220 comprises an arc-shaped groove 221 and a placement table 222 connected with the arc-shaped groove 221 perpendicularly, a soft guide wire groove 223 for clamping the catheter body 710 connected with the catheter handle head 721 is arranged on the placement table 222, the soft guide wire groove 223 is made of rubber, the guide wire groove 223 is detachably connected with the placement table 222, different sizes of guide wire grooves 223 can be replaced to adapt to different sizes of catheter bodies 710, a detachable rubber pad 224 is arranged on the arc-shaped groove 221, the outer circle of the catheter handle head 721 is in soft contact with the arc-shaped groove 221 through the rubber pad 224, so as to avoid the catheter handle head 721 scratching and damaging the catheter, and further enhance the stability, a reinforcing rib connected with the base 210 is arranged on the outer wall surface of the bottom of the arc-shaped groove 221, so as to improve the stability of the arc-shaped groove 221;

[0034] The clamping part 230 is arranged on both sides of the clamping groove 220 and used for clamping the catheter handle head 721, wherein the two clamping parts 230 can move towards or away from each other, so as to adjust the distance between the two clamping parts 230.

[0035] Wherein, on both sides of the clamping groove 220, there are clamping part containing grooves 240 for placing and moving the clamping parts 230, the clamping parts 230 move linearly along the clamping part containing grooves 240, avoiding misplacement when the two clamping parts 230 move towards or away from each other, ensuring that the centers of the two clamping parts 230 correspond, and improving the stability of the clamping parts 230 clamping the catheter handle head 721.

[0036] Wherein, a gap is left between the base 210 and the bottom plate 100 to avoid the movement of the head clamping mechanism 200 being blocked.

[0037] The application can accommodate catheters of different radial sizes through the two clamping parts 230 clamping the catheter handle head 721, and has strong versatility.

[0038] For example, in the interventional surgery catheter fixing frame provided in one embodiment, as shown in Figures 2-3 The clamping part 230 includes:

[0039] The clamping head 231 abuts against the outer wall of the catheter handle head 721, the clamping head 231 is made of rubber, realizing soft contact between the clamping head 231 and the catheter handle head 721, protecting the catheter, avoiding scratching the catheter handle head 721 by the clamping head 231, improving clamping firmness, further enhancing stability, and being applicable to catheters of different models and sizes.

[0040] The bottom support 232 is provided with a latch 2321, and the clamping head 231 is provided with an adjustable insertion hole through which the latch 2321 passes, to facilitate replacing clamping heads 231 of different sizes to meet the needs of clamping catheters of different sizes, the bottom support 232 and the clamping head 231 are detachably connected through the latch 2321, and the bottom support 232 is a soft structure similar to a silica gel pad.

[0041] The adjusting screw 233 passes through the clamping part containing groove 240 and abuts against the bottom support 232 at one end, and is provided with a press-type hinge 234 at the other end, the distance between the two clamping heads 231 is adjusted by pressing the press-type hinge 234; an adjusting nut 235 is vertically arranged radially at the abutting end of the adjusting screw 233 and the bottom support 232, during daily use, the distance between the two clamping heads 231 is manually adjusted by pushing and pulling the adjusting nut 235 with fingers, when it is necessary to fix the two clamping heads 235 at a specific position, the two clamping heads 235 are fixed to the desired position by tightening or loosening the adjusting nut 235.

[0042] Specifically, the press-type hinge 234, i.e. a spring lock, has two states of opening and closing. By pressing the press-type hinge 234, the two clamping heads 231 are controlled to move close to or away from each other to clamp the catheter handle head 721. When the press-type hinge 234 is in the closed state, the spacing between the two clamping heads 231 can be manually adjusted by pushing and pulling the adjusting nut 235 radially arranged at the abutting end of the adjusting screw 233 with the bottom support 232, and the two clamping heads 231 are fixed to the required position by tightening or loosening the adjusting nut 235. Intraoperative single-handed operation can complete the required placement and removal operation of the catheter in the operation by adjusting the tightness of the clamping mechanism, which is convenient, efficient and convenient for clinical operation of medical staff.

[0043] For example, in the catheter fixing frame provided in an embodiment, as shown in Figures 4-5 The tail clamping mechanism 300 includes:

[0044] The support seat 310 is vertically arranged on the surface of the support plate 100.

[0045] The tail holding groove 320 is connected with the support seat 310 and used for placing the catheter handle tail 722. The tail holding groove 320 is a U-shaped groove and includes a semi-cylindrical groove 321, a semi-conical groove 322 and a semi-cylindrical groove 323 which are sequentially and smoothly connected in the direction from the catheter handle head 721 to the catheter handle tail 722. A pad 324 is arranged at the center of the semi-cylindrical groove 321. The pad 324 is made of rubber and is used for protecting the catheter to avoid scratching the catheter handle tail 722, improving the clamping firmness and further enhancing the stability.

[0046] The tightening steel sheet 330 is arranged on the outer wall surface of the tail holding groove 320. Specifically, the tightening steel sheet 330 is arranged on the outer wall surface of the semi-cylindrical groove 321 and includes two symmetrically arranged arc-shaped sheets 331. The arc-shaped sheets 331 can slide along the outer wall surface of the tail holding groove 320 and extend from both ends of the tail holding groove 320 to clamp the catheter handle tail 722.

[0047] The tail holding groove 320 is a U-shaped groove, i.e. is designed to be deepened in the groove depth direction, which overcomes the defects of the C-shaped groove structure, such as low clamping firmness and poor wrapping performance. The tail holding groove 320 includes the semi-cylindrical groove 321, the semi-conical groove 322 and the semi-cylindrical groove 323 which are sequentially and smoothly connected in the direction from the catheter handle head 721 to the catheter handle tail 722. The structure design has a guiding effect and can adapt to the placement of the tail end of the interventional catheter with different radial dimensions and axial lengths, thereby improving the clamping firmness of the tail clamping mechanism 300.

[0048] For example, in the catheter fixing frame provided in an embodiment, as shown inFigures 4-5 As shown, the arc-shaped sheet 331 is connected with the tail holding groove 320 through the screw 332, and an arc-shaped sliding groove 3311 is arranged on the arc-shaped sheet 331 to allow the screw 332 to pass through when the arc-shaped sheet 331 slides along the outer wall surface of the tail holding groove 320; a push handle 3312 is arranged at the end of the arc-shaped sheet 331 close to the other arc-shaped sheet 331, a pull handle 3313 is arranged at the free end of the arc-shaped sheet 331, and a rubber pad 3314 is arranged at the free end of the arc-shaped sheet 331 close to the surface of the tail holding groove 320, the rubber pad 3314 is fixedly connected with the arc-shaped sheet 331 through the screw, and the arc-shaped sheet 331 is in soft contact with the tail handle 722 of the catheter handle through the rubber pad 3314, so that the arc-shaped sheet 331 does not scratch the tail handle 722 of the catheter handle to cause damage to the catheter, thereby protecting the catheter and improving the clamping firmness and further enhancing the stability.

[0049] When the tail handle 722 of the catheter handle is placed in the tail holding groove 320, the push handle 3312 of the two arc-shaped sheets 331 is pushed or the pull handle 3313 at the free end of the arc-shaped sheet 331 is pulled, and the two arc-shaped sheets 331 slide upward along the outer wall of the tail holding groove 320, so as to be wrapped around the outer periphery of the tail handle 722 of the catheter handle, thereby fixing the tail handle 722 of the catheter handle.

[0050] For example, in the catheter fixing frame provided in one embodiment, as shown in Figures 4-5 As shown, a strap limiting groove 325 is arranged on the outer wall surface of the tail holding groove 320, and the tail clamping mechanism 300 is connected with the tail handle 722 of the catheter handle through the strap 800.

[0051] According to the above embodiment, the tail handle 722 of the catheter handle can be quickly and tightly connected with the tail clamping mechanism 300 through the strap 800, and the stability is improved.

[0052] Specifically, the strap limiting groove 325 is arranged on the outer wall surface of the semicylindrical groove 323 of the tail holding groove 320, and the strap 800 can be clamped on the outer wall surface of the semicylindrical groove 321 or in the strap limiting groove 325. The strap 800 and the tightening steel sheet 330 are two ways to tightly connect the tail handle 722 of the catheter handle with the tail clamping mechanism 300, and they can be used alone or in combination: the tightening steel sheet 330 is arranged on the outer wall surface of the semicylindrical groove 321 alone to tightly connect the tail handle 722 of the catheter handle with the tail clamping mechanism 300; or the tightening steel sheet 330 is arranged on the outer wall surface of the semicylindrical groove 321 and the strap 800 is clamped in the strap limiting groove 325, and the two are combined to tightly connect the tail handle 722 of the catheter handle with the tail clamping mechanism 300; or the strap 800 is clamped in the strap limiting groove 325 and on the outer wall surface of the semicylindrical groove 321 to tightly connect the tail handle 722 of the catheter handle with the tail clamping mechanism 300.

[0053] For example, in one embodiment of the catheter fixing frame for interventional surgery, as shown in Figure 1 、 4 The lifting mechanism 600 is arranged between the support seat 310 of the tail clamping mechanism 300 and the support plate 100, and comprises:

[0054] A mounting seat 610 is vertically arranged on the surface of the support plate 100;

[0055] A lifting screw 620 is vertically connected between the mounting seat 610 and the support seat 310 of the tail clamping mechanism 300 and located at the middle part of the mounting seat 610, and the height of the tail clamping mechanism 300 in the direction perpendicular to the surface of the support plate 100 is adjusted by rotating the lifting screw 620;

[0056] A guide steel pipe 630 is vertically connected between the mounting seat 610 and the support seat 310 of the tail clamping mechanism 300 and located at both sides of the support seat 310, and a spring is sleeved on the guide steel pipe 630.

[0057] The mounting seat 610 and the bottom plate 100 are left with a certain gap to avoid the movement of the tail clamping mechanism 300 being blocked.

[0058] By arranging the lifting mechanism 600 on the tail clamping mechanism 300, the supporting height of the tail clamping mechanism 300 can be adjusted to adapt to catheters of different sizes, and the head part 721 and the tail part 722 of the catheter handle can be ensured to be on the same horizontal plane, avoiding the catheter being placed insecurely due to the inclination of the catheter and the damage of the catheter caused by scratching.

[0059] For example, in one embodiment of the catheter fixing frame for interventional surgery, as shown in Figure 6 The head clamping mechanism 200 and the tail clamping mechanism 300 are connected through the distance adjusting mechanism 400, and the distance adjusting mechanism 400 comprises:

[0060] A guide rod 410 is arranged inside the support plate 100, arranged along the axial direction of the catheter 700 and penetrates through the support plate 100, and the base 210 of the head clamping mechanism 200 and the mounting seat 610 of the lifting mechanism 600 are arranged on the guide rod 410 and can slide along the guide rod 410 to adjust the distance between the head clamping mechanism 200 and the tail clamping mechanism 300;

[0061] Two distance adjusting screws 420 corresponding to the head clamping mechanism 200 and the tail clamping mechanism 300, respectively, are arranged inside the support plate 100 along the direction perpendicular to the axial direction of the catheter 700 and extend from the side of the support plate 100. A sliding groove 110 is arranged on the side of the support plate 100 for the movement of the distance adjusting screw 420. The free end of the distance adjusting screw 420 is connected to the base 210 and the mounting seat 610, respectively. The distance adjusting screw 420 is tightened to limit the head clamping mechanism 200 and the tail clamping mechanism 300.

[0062] According to the above embodiment, the distance between the head clamping mechanism 200 and the tail clamping mechanism 300 can be adjusted by the distance adjusting mechanism 400, so as to meet the catheter support of different axial lengths. The head clamping mechanism 200 and the tail clamping mechanism 300 are arranged on the guide rod 410 and slide along the guide rod 410, so as to ensure that the head clamping mechanism 200 and the tail clamping mechanism 300 move on the same horizontal plane and are centered.

[0063] For example, in an embodiment, the interventional surgery catheter fixing frame comprises a support plate 100, a head clamping mechanism 200, a tail clamping mechanism 300, a guide rod 410, a distance adjusting mechanism 400, a lifting mechanism 600 and a leveling mechanism 500. Figure 1 As shown in the drawings, a cover plate 120 is arranged on the base 210 of the head clamping mechanism 200 and the mounting seat 610 of the lifting mechanism 600. A scale line 121 is arranged on the side of the cover plate 120. The distance between the head clamping mechanism 200 and the tail clamping mechanism 300 can be determined by the scale line 121. The scale line 121 can also help the doctor to know the moving depth of the interventional catheter in the patient's body, so that the doctor can have a rough idea. The length of the catheter handle 720 can also be measured, so as to facilitate the medical staff to find the best holding position. Foreign matters can be prevented from entering the guide rail by the cover plate 120, so as to affect the normal use and make the fixing frame more beautiful.

[0064] For example, in an embodiment, the interventional surgery catheter fixing frame comprises a support plate 100, a head clamping mechanism 200, a tail clamping mechanism 300, a guide rod 410, a distance adjusting mechanism 400, a lifting mechanism 600 and a leveling mechanism 500. Figure 6 As shown in the drawings, the leveling mechanism 500 comprises adjusting nuts 510 arranged at the four corners of the bottom surface of the support plate 100. The adjusting nuts 510 are used to level the support plate 100 and improve the adaptability of the fixing frame to the placement position. A sleeve is arranged outside the adjusting nut 510 to protect the adjusting nut 510 and make the adjusting nut 510 not exposed, so as to increase the sanitary standard.

[0065] The interventional surgery catheter fixing frame of the present application is provided with a catheter placement direction mark 900 on the surface of the support plate 100. The catheter handle head 721 and the catheter handle tail 722 can be accurately clamped on the head clamping mechanism 200 and the tail clamping mechanism 300, respectively, so as to avoid the reverse placement of the catheter direction.
