AI Technical Summary
In orthopedic surgery, when the nail needs to be nailed into the bone at a specific angle, the original fixed handle cannot rotate, resulting in blocking and inconvenient operation during drilling.
A rotatable guide is designed, including a fixing seat, a handle, a guide sleeve and a limiting pin. The top of the guide sleeve fits the cylindrical cavity of the fixing seat and maintains the connection between the fixing seat and the guide sleeve through a limiting pin, allowing the guide sleeve to rotate on the fixing seat.
Through the rotatable design, the operator can drill holes at any angle, which improves the flexibility and efficiency of surgical operations and avoids the problem of handle obstruction.

Abstract
Description
Technical Field
[0001] The present application relates to orthopedic instruments, and in particular to a rotatable guide. Background Art
[0002] Before orthopedic nailing, it is usually necessary to drill a slightly smaller hole through a guide sleeve, and then fix the fracture end through the cooperation of the nail and the plate. In actual operation, the nail may need to be driven into the bone at a certain angle. At this time, the original handle is fixed and cannot rotate, which may block the drilling and affect the surgical operation. Utility Model Content
[0003] The utility model aims to provide a rotatable guide device, which is convenient for limiting the guide sleeve, so that a hole can be drilled at any angle.
[0004] An embodiment of the present application discloses a rotatable guide, including a fixed seat, one side of the fixed seat is bent and protruded upward to form a handle, a cylindrical cavity is formed inside the fixed seat, and the guide sleeve also includes a guide sleeve, the top of the guide sleeve is inserted into the cylindrical cavity, the guide sleeve is formed with a circular annular groove along the annular direction near the top, a positioning notch is formed at the end of the fixed seat away from the handle, and the guide sleeve also includes a limit pin, which is inserted into the positioning notch and the circular annular groove.
[0005] Preferably, in the above-mentioned rotatable guide, the handle is bent upward at an angle of 20-70°.
[0006] Preferably, in the above-mentioned rotatable guide, a conical cavity is formed above the cylindrical cavity, the bottom diameter of the conical cavity is smaller than the inner diameter of the cylindrical cavity, and the top of the guide sleeve is abutted against the bottom surface of the conical cavity.
[0007] Preferably, in the above-mentioned rotatable guide, a driving component is inserted into the truncated cone cavity to drive the guide sleeve to drill a hole.
[0008] Preferably, in the above-mentioned rotatable guide, the bottom end of the guide sleeve is formed with evenly distributed teeth.
[0009] Preferably, in the above-mentioned rotatable guide, the handle is a wing-shaped arc strip.
[0010] Compared with the prior art, the advantage of this technical solution is that the limit pin is first inserted, and the guide sleeve and the fixed seat will not be separated. At the same time, the guide sleeve can be kept rotating around the axis, and the handle is adjusted to the required position. The drive component is inserted to drive the guide sleeve to rotate, and there is a better operating angle to facilitate drilling holes in the bottom tooth body. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments recorded in the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.
[0012] Figure 1 Shown is a schematic diagram of a rotatable guide in an embodiment of the utility model;
[0013] Figure 2 Shown is a disassembled view of the rotatable guide in an embodiment of the utility model. DETAILED DESCRIPTION
[0014] The following will be combined with the drawings in the embodiments of the utility model to describe the technical solutions in the embodiments of the utility model in detail. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0015] Combination Figure 1-Figure 2 As shown, the rotatable guide 100 includes a fixed seat 101, one side of the fixed seat 101 is bent upward to form a handle 102, a cylindrical cavity 103 is formed inside the fixed seat 101, and a guide sleeve 104 is also included. The top of the guide sleeve 104 is inserted into the cylindrical cavity 103, and the guide sleeve 104 is formed with a circular groove 105 along the annular recess near the top. A positioning notch 106 is formed at the end of the fixed seat 101 away from the handle 102, and a limit pin 107 is also included. The limit pin 107 is inserted into the positioning notch 106 and the circular groove 105. The handle 102 is bent upward at an angle of 20-70°. A truncated cone cavity 108 is formed above the cylindrical cavity 103, and the bottom surface diameter of the truncated cone cavity 108 is smaller than the inner diameter of the cylindrical cavity 103. The top of the guide sleeve 104 is against the bottom surface of the truncated cone cavity 108. The driving component is inserted into the truncated cone cavity 108 to drive the guide sleeve 104 to drill a hole. The bottom end of the guide sleeve 104 is formed with uniformly distributed teeth 109. The handle 102 is a wing-shaped arc strip.
[0016] In this embodiment, the limit pin is first inserted, and the guide sleeve and the fixed seat will not be separated. At the same time, the guide sleeve can be kept rotating around the axis. The handle is adjusted to the required position, and the drive component is inserted to drive the guide sleeve to rotate, which has a better operating angle and is convenient for drilling holes in the bottom gear body. At the same time, the bent handle can be rotated to prevent the body from being blocked. The arc handle has a better feel.
[0017] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
[0018] The above is only a specific implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
