The technical field is as follows:
the utility model relates to a femoral neck forceps holder guider, which belongs to a medical auxiliary device, in particular to a positioning device used in the operation treatment of femoral neck fracture.
Background art:
femoral neck fractures in young adults account for 3-10% of all hip fractures and treatment remains a challenge for orthopedic surgeons. The reoperation rate of these fractures after fixation is still high due to avascular necrosis of the femoral head, non-union, failure of internal fixation and removal of the bone. The incidence of complications of displaced fractures is high and in the management of these fractures, careful consideration of the injury factor, fracture type, physiological age, timing of surgery, capsulotomy, and choice of implant is required. For complex femoral neck fractures, in order to increase the success rate of internal fixation, incisional reduction internal fixation can be used to achieve better reduction, even joint replacement.
For femoral neck fractures, cannulated screw fixation remains the most common form of fixation. The hollow screw is adopted for fixing, firstly, 2-3 guide pins need to be correctly driven in before the hollow screw is driven in, and then the hollow screw is screwed in through the guide pins. This method requires the surgeon to control the direction of the guide pin and the angle precisely by experience. As the diameter of the femoral head is smaller, the fault-tolerant area for nailing the guide pin is very small, an operator needs to drive 2-3 guide pins through the femoral neck, and the guide pins are distributed as dispersedly as possible to more stably fix the fracture, which causes great inconvenience to the operator and needs to accumulate a lot of experience to increase the accuracy. The more complex the fracture, the more accurate reduction and accurate fixation are required, the more complex the fracture types of patients who are often subjected to incision reduction are, and the more accurate control of the position of the guide pin is required.
The utility model has the following contents:
the utility model aims to provide a femoral neck clamp guide which has a simple structure and can ensure that a guide pin is accurately fixed.
A femoral neck forceps clip guide is characterized by comprising a handle, a forceps holder and a guide pin barrel, wherein the handle comprises a handle rod, the handle rod is a rod piece with the middle straight and two bent ends, one end of the handle rod is fixedly connected with a sleeve, the axial direction of the sleeve is parallel to the handle rod, and the other end of the handle rod is provided with a hollow connecting piece; the hollow connecting piece is provided with a through hole, and the axial direction of the through hole is vertical to the handle rod; a guide pin cylinder penetrates through the central hole of the sleeve; the hollow connecting piece is a connecting block with a through hole, and a forceps holder is connected in the through hole of the hollow connecting piece.
The forceps holder include two structures the same, opposite direction's holder, the holder constitute by straight connecting rod and centre gripping crooked pole, straight connecting rod and centre gripping crooked pole structure as an organic whole.
The cross section of the straight connecting rod is rectangular.
The cross section of the straight connecting rod is square.
The through hole of the hollow connecting piece is a square through hole.
The needle guide cylinder is a cylindrical cylinder with a cylinder cap at one end, and a central hole of the cylindrical cylinder is a thin through hole; the surface of the other end of the needle guide cylinder is an inclined plane.
The outer diameter of the cylinder cap is larger than that of the sleeve.
The utility model has simple structure, improves the direction accuracy and the accurate determination of the positioning of the guide needle cylinder by changing the position of the fulcrum, doubles the fault tolerance, increases the distribution hit rate of the guide needle at the femoral neck part, reduces the operation difficulty and can effectively improve the fixing effect of the operation.

The specific implementation mode is as follows:
the present invention will be further described with reference to fig. 1, 2, 3, 4 and 5:
the design concept of the utility model is to increase the stability and the directivity of the needle guiding cylinder by increasing the pivot of the needle guiding cylinder so as to ensure convenient operation and accurate positioning when the guide needle is punched by the guide needle cylinder.
In order to achieve the object of the present invention, in the present embodiment, the present invention comprises three parts: handle 1, clipper 2 and guide pin barrel 3.
As shown in fig. 2, the handle 1 comprises a handle bar 13, which is a rod with a straight middle part and two bent ends, and in order to increase the fulcrum of the utility model, a sleeve 11 is fixedly connected to one end of the handle bar, and the sleeve 11 is used for guiding the syringe, so that the axial direction of the sleeve 11 is parallel to the handle bar.
The other end of the handle bar is provided with a hollow connector 15. The hollow connecting member 15 is provided for fixing the clamper 2. Thus, the hollow connecting piece is provided with a through hole 14, the axial direction of which is perpendicular to the handle bar. In this embodiment, the hollow connecting member 15 is a connecting block with a through hole 14, and a clamper 2 is connected to the through hole 14 of the hollow connecting member.
In this embodiment, the forceps holder includes two clamping members with the same structure and opposite directions, the clamping member is composed of a straight connecting rod 21 and a clamping curved rod 22, and the straight connecting rod 21 and the clamping curved rod 22 are of an integral structure.
The bore of the through bore 14 of the hollow connector is sized to match the straight connecting rod 21 portion of the forceps holder 2. When the clamp is installed, the straight connecting rod 21 is partially inserted into the through hole 14 of the hollow connecting member, and the structure is convenient to install and disassemble.
The straight connecting rod 21 has a rectangular or square cross section so that the through hole 14 of the matching connecting member can be a square through hole.
In this embodiment, the guide pin cylinder 3 is a cylindrical cylinder with a cylinder cap 31 at one end, and the central hole of the cylindrical cylinder is a thin through hole 32; the surface of the other end of the guide pin cylinder 3 is a slope 33. The guide pin cylinder 3 of the utility model is inserted into the central hole 12 of the sleeve 11, and one end of the guide pin cylinder 3 can be clamped at the inserting end of the sleeve because the outer diameter of the cylinder cap 31 is larger than that of the sleeve 11. The other end of the needle guiding cylinder 3 only penetrates out of the sleeve, so that the end of the needle guiding cylinder 3 with the inclined surface 33 extends out of the channel, and when in use, the inclined surface enlarges the rotor part, thereby realizing accurate positioning.
The method of use of the present invention, as shown in FIG. 5:
the patient is placed in a horizontal position, an anterior-lateral incision is made on the hip joint, skin tissues and muscles are pulled open, the femoral neck 4 is exposed for operation, and the operation can be carried out outside the capsule without cutting the joint capsule for restoration. The part of the handle connecting forceps of the utility model is placed in the middle of the flat area in front of the femoral neck, and the straight connecting rod 21 part of the handle of the forceps is inserted into the through hole 14 of the hollow connecting piece. Different positions can be adjusted according to requirements, so that the tail end of the sleeve can be close to the femoral moment as much as possible, and the sleeve is fixed after the position is adjusted. And inserting a guide needle cylinder into the sleeve, rotating one end of the guide needle cylinder with an inclined plane to a proper angle to be close to the inclined plane at the lower end of the large rotor, and driving in the guide needle along the guide direction of the guide needle cylinder to complete the driving in of the guide needle.
