Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and specifically relates to a titanium cable separator. Background Art

[0002] In orthopedic fracture surgery, especially in internal fixation surgery for spiral fractures of long bones of the limbs, titanium cables are usually used to tie and fix the fracture ends. After the fracture heals, the titanium cable needs to be removed. In the process of removing the titanium cable, the titanium cable should be cut first, then the titanium cable and human muscle tissue should be separated, and finally the end of the separated titanium cable located in the human body should be cut off to remove the titanium cable. Current surgical instruments cannot separate the titanium cable and human components well, and may cause great harm to the human body during the separation of the titanium cable. Moreover, since the surgical incision for removing the titanium cable in the body is often smaller than the incision of the previous fracture internal fixation surgery, this increases the difficulty of separating the titanium cable. When the callus is located in the blind spot of the surgical field of view, general surgical instruments cannot effectively separate the titanium cable.

[0003] Therefore, in view of the above technical problems, it is necessary to provide a titanium cable separator. Utility Model Content

[0035] The technical solution of the present utility model will be described below in conjunction with the accompanying drawings.

[0036] Reference Figure 1 to Figure 4 As shown, a titanium cable separator in a specific embodiment of the utility model comprises: a separator body 1, a flexible tube 2, a clamp assembly 3, a guide wire 4, and a driving member 5. The flexible tube 2 is mounted on the separator body 1; the clamp assembly 3 is arranged at the distal end of the flexible tube 2, the clamp assembly 3 comprises a first clamp 31 and a second clamp 32 which cooperate with each other, the distal ends of the first clamp 31 and the second clamp 32 are both provided with a cutting edge 33, and the first clamp 31 and the second clamp 32 are enclosed to form a jaw; the guide wire 4 is arranged in the separator body 1, the first end of the guide wire 4 is fixedly mounted with one of the first clamp 31 or the second clamp 32, and the other of the first clamp 31 or the second clamp 32 is fixedly mounted with the distal end of the flexible tube 2; the driving member 5 is hingedly mounted on the separator body 1, the second end of the guide wire 4 is fixedly mounted with the driving member 5, and under the action of the driving member 5, the first clamp 31 and the second clamp 32 can rotate relative to each other to open or close the jaw.

[0037] The flexible tube 2 may be directly fixedly installed on the separator body 1, or the flexible tube 2 may be indirectly fixedly installed on the separator body 1 through a clamp tube 6 (as described below).

[0038] According to this design, the titanium cable separator is continuously inserted into the human body, that is, the clamp assembly 3 is set on the cut titanium cable and continuously inserted into the human body. During the insertion process, the titanium cable moves more and more toward the inside of the titanium cable separator, that is, the titanium cable moves into the flexible member. Since the flexible member is flexible and can be deformed, and the titanium cable is hard, the flexible member can be attached to the original shape of the titanium cable to determine the shape of the flexible member. In the process of continuously inserting the distal end of the titanium cable separator into the human body, the distal ends of the first clamp 31 and the second clamp 32 are both provided with a cutting edge 33, and the human tissue adhered to the titanium cable can be separated by the cutting edge 33. At the same time, the operator can rotate the driving member 5 (let the driving member 5 rotate along the hinge between it and the separator body 1) to pull the guide wire 4 away from the proximal direction. The first clamp 31 or the second clamp 32 rotates relatively under the action of gravity until it is tightened by the guide wire 4 again. The jaws formed by the first clamp 31 and the second clamp 32 open, allowing the titanium cable that is completely separated from the human tissue to more easily enter the flexible member, thereby completing the separation of the titanium cable and the human tissue and reducing the damage to the human body.

[0039] Specifically, in order to install the first clamp 31 and the second clamp 32 so that they can rotate relative to each other under the premise that the driving member 5 controls the movement of the guide wire 4, refer to Figure 1-2 As shown, in this embodiment, the first clamp 31 is fixedly installed with the flexible tube 2 , and the second clamp 32 is fixedly installed with the first end of the guide wire 4 .

[0040] Among them, in order to form a jaw, so as to control the opening and closing state of the jaw, to facilitate the titanium cable to enter the flexible member after entering the clamp assembly 3, refer to Figures 4 to 6 As shown, the first clamp 31 in this embodiment includes a tube body 311 fixedly mounted on the flexible tube 2 and a first clamp body 312 connected to the tube body 311 and extending toward the distal end, and the second clamp 32 includes a second clamp body 321 matched with the first clamp body 312. The first clamp body 312 and the second clamp body 321 enclose a jaw, and the inner diameter of the jaw is the same as the inner diameter of the tube body 311. Preferably, the inner diameter of the jaw is smaller than the inner diameter of the tube body 311, and the inner diameter of the tube body 311 is smaller than the inner diameter of the flexible tube 2. According to this design, it is prevented that the titanium cable will be blocked by the inner wall of the tube body 311 or the flexible tube 2 during the process of entering the titanium cable separator from the distal end of the jaw, and the titanium cable completely separated from the human tissue through the cutting edge 33 cannot completely enter the flexible member, and the cutting edge 33 cannot contact the titanium cable that is not completely separated from the human tissue, which ultimately leads to incomplete separation. In this embodiment, the human tissue and the titanium cable can be completely separated by the cutting edge 33, and the entry of the separated titanium cable can be facilitated by opening or closing the jaws, thereby preventing the titanium cable from bending and deforming under the pressure of the titanium cable separator, thereby effectively reducing the difficulty of separation and the damage to the human body.

[0041] Preferably, in order to ensure the stability of jaw opening or closing, refer to Figure 6 As shown, in this embodiment, when the jaws are in the open state, the second jaw body 321 abuts against the tube body 311 and is separated from the first jaw body 312. When the jaws are open, if the wire is too loose, the second jaw body 321 and the tube body 311 will be separated, and ultimately only the cutting edge 33 of the first jaw body 312 can work, which is unreliable. Therefore, when the jaws are in the closed state, the second jaw body 321 in this embodiment abuts against both the tube body 311 and the first jaw body 312.

[0042] In order to make the jaws open as wide as possible, so as to facilitate the titanium cable to enter the jaws and separate the titanium cable from human tissue, refer to Figure 4 , Figure 6 As shown, on a plane perpendicular to the axis of the tube body 311 , the orthographic projection of the first clamp body 312 and the orthographic projection of the second clamp body 321 in this embodiment are both arc-shaped and 180°.

[0043] In order to avoid the position deviation of the first jaw body 312 and the second jaw body 321 during the opening or closing of the jaws, Figures 4 to 7 As shown, in this embodiment, the tube body 311 is provided with an inserting groove 3111, and the second clamp body 321 is provided with an inserting portion 322. According to this design, the second clamp body 321 is inserted into the first clamp body 312.

[0044] Preferably, refer to Figure 5 , Figure 6 As shown, the plug-in portion 322 in this embodiment is provided with a chamfered surface 3221, and when the jaws are in the open state, the chamfered surface 3221 abuts against the tube body 311. According to this design, the stability and reliability of the jaws in the open state are improved.

[0045] In addition, refer to Figure 2 , Figure 3 As shown, in order to fix the flexible tube 2 and the separator body 1, the titanium cable separator in this embodiment further includes a clamp tube 6, the proximal end of the clamp tube 6 is fixedly installed in the separator body 1, the distal end of the clamp tube 6 extends out of the separator body 1, and a first mounting groove 61 is provided on the inner wall of the distal end of the clamp tube 6, and the flexible tube 2 is fixedly installed in the first mounting groove 61. According to this design, the end of the flexible tube 2 is fixedly installed in the first mounting groove 61, and the flexible tube 2 is installed on the separator body 1 through the clamp tube 6, and the clamp tube 6 is provided with a through hole for the guide wire 4 to pass through.

[0046] Preferably, refer to Figure 2 , Figure 8 As shown, the titanium cable separator in this embodiment also includes a reset member 7 disposed between the driving member 5 and the clamp tube 6. According to this design, when the distance between the driving member 5 and the clamp tube 6 becomes smaller, that is, the guide wire 4 is loosened, so that the second clamp 32 rotates relative to the first clamp 31 along the first direction to open the jaws, the reset member 7 can provide the driving member 5 with an elastic force away from the clamp tube 6, so that the driving member 5 is reset, the guide wire 4 is tightened, and the second clamp 32 rotates relative to the first clamp 31 along the second direction opposite to the first direction to close the jaws. Among them, the reset member 7 can be any structure that can provide elastic force, such as a spring, a shrapnel, an airbag, etc. In order to install the reset member 7 on the clamp tube 6, the inner wall of the proximal end of the clamp tube 6 in this embodiment is provided with a second mounting groove 62, and the end of the reset member 7 is fixedly installed in the second mounting groove 62.

[0047] The driving member 5 is hinged to the separator body 1 through the fixing member 8. The driving member 5 has two ends, one of which is in contact with the reset member 7 and opposite to the position of the clamp tube 6, and the other end is suspended, and the installation position of the fixing member 8 is located between the two ends. The fixing member 8 can be any structure such as a bolt, a nut, a rivet, a screw, etc. for fixing two parts, which can be understood and accepted by those skilled in the art.

[0048] In summary, the working principle of the titanium cable separator in the utility model is:

[0049] After the operation of cutting the titanium cable is completed, the separator body 1 and the driving member 5 of the handheld titanium cable separator are held, and an external force is applied to the driving member 5 to rotate the end of the driving member 5 opposite to the clamp tube 6 toward the clamp tube 6, so that the guide wire 4 is loosened, and the second clamp 32 is rotated relative to the first clamp 31 along the first direction, so that the jaws are opened, and the titanium cable enters the jaws; along the jaws, the operator controls the titanium cable separator to continuously enter the human body, so that the titanium cable enters the first clamp body 312 and the second clamp body 321, the tube body 311, the flexible tube 2, and the clamp tube 6. In this process, since the distal ends of the first clamp body 312 and the second clamp body 321 are both provided with a cutting edge 33, the opening and closing of the first clamp body 312 and the second clamp body 321 by the movement of the driving member 5 can effectively separate the titanium cable and human tissue, making it easier for the titanium cable to enter the interior of the titanium cable separator. When the titanium cable enters the titanium cable separator, the titanium cable wraps around the bone and presents a curved shape. The flexible tube 2 is flexible and can enter the human body along the titanium cable without causing any impact on the human body. When the titanium cable separator enters a certain position in the human body, that is, where the titanium cable is wrapped by the bone callus, the titanium cable separator is withdrawn from the human body to facilitate the operator to perform subsequent surgical operations.

[0050] It can be seen from the above technical solutions that the utility model has the following beneficial effects:

[0051] The utility model provides a titanium cable separator, which controls the titanium cable separator to move forward so as to separate the titanium cable and human tissue through a cutting edge, and drives a guide wire through a driving member to drive a jaw formed by a first clamp and a second clamp to open or close, so that the separated titanium cable can enter the flexible member more easily, thereby completing the separation of the titanium cable and human tissue, reducing damage to the human body, and improving the separation effect and safety of the separated titanium cable.

[0052] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0053] In addition, it should be understood that although the present specification is described according to embodiments, not every embodiment contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
