Problems solved by technology

Moreover, the operation relies heavily on the experience of the doctor, and the position reached by the puncture is not necessarily very accurate.
This method based solely on feeling is not accurate enough, and often requires extensive surgical experience and repeated fluoroscopy to complete; it not only increases the operation time, but also exposes medical staff and patients to X-ray radiation for many times.
If the positioning is not accurate, it will inevitably cause unnecessary structural damage, thereby increasing damage

Embodiment 1

[0079] like Figure 1-3 As shown, a detachable and assembled arc-shaped precise positioning device includes a support unit, a three-dimensional adjustment unit and a guide positioning unit.

[0080] Its support unit includes an L-shaped base composed of a base and a vertical guide rail 1 perpendicular to the base. The base is provided with rollers and a brake device that can fix the ground, which is convenient for moving and fixing the detachable and assembled arc-shaped precise positioning equipment. On the vertical guide rail 1, a storage table 2 can be installed horizontally, which is used to place a spare instrument box during the operation, and the actual size of the storage table is adjusted according to the actual situation of the operation.

[0081] In this embodiment, the three-dimensional adjustment unit includes a lift adjustment unit and a horizontal adjustment unit.

[0082] The lifting adjustment unit includes a first fixed block 3 arranged on the vertical guide...

Embodiment 2

[0106] like Figure 7 As shown, the difference from Embodiment 1 is that there are two locators, namely a vertical locator 11 and a horizontal locator 12, the horizontal locator 12 and the vertical locator 11 are all installed on the arc-shaped guide rail 22, and The long axes of the rays that two locators send and the holder 23 are all parallel or coincident with the radial line of the arc-shaped track, and the three lines intersect at one point, and form a plane, and the formed plane and the arc-shaped track 22 The arc-shaped plane coincides. The first embodiment is as Figure 7 As shown in A, the two locators can be embedded in the arc-shaped track 22, and the connection mode of the third slider, the guide rod and the holder can be as follows Figure 7 Shown in B and 7C. The second embodiment is as Figure 7 D shows that the two locators can be connected outside the arc-shaped track 22, the rays emitted by the two locators and the long axis of the holder 23 are all para...

Embodiment 3

[0108] The difference from Embodiment 1 is that in this embodiment, the structure of the support unit and the three-dimensional adjustment unit is different.

[0109] The first implementation method: as Figure 8 , Figure 9 As shown, the support unit in this embodiment is composed of multiple fixed arms, and the two fixed arms are hinged by universal joints. In this embodiment, there are three fixed arms, respectively the first fixed arm 38, the second fixed arm 39, and the third fixed arm 40, wherein one end of the first fixed arm 38 is fixed on the roof or the wall, and the first fixed arm 38 the other end is hinged with one end of the second fixed arm 39 through the first universal joint 41, and the other end of the second fixed arm 39 is hinged with one end of the third fixed arm 40 through the second universal joint 42, and the third fixed arm 40 The other end is connected with the first slider 24. The first slider 24 is driven by the fixed arm to move up and down, le...

Abstract

The invention relates to detachable-mountable arc-shaped precise positioning equipment, which includes a supporting unit, a three-dimensional regulating unit connected to the supporting unit, and a guidance positioning unit. The guidance positioning unit includes an arc-shaped rail, a guide rod, a holder, and positioning meters. A second sliding block is connected to the three-dimensional regulating unit; the arc-shaped rail is arranged and slides on the second sliding block, and can be subjected to in-situ rotation around a vertical axis at any angle; the three-dimensional regulating unit drives the arc-shaped rail to move in three dimensions of up-down, left-right, and front-back dimensions; the guide rod can slide along the arc-shaped rail and moves long a long axial direction of the guide rod; and the holder is arranged on the guide rod for fixing a surgical instrument. There are two positioning meters, and rays sent by the two positioning meters, along with a long axis of the holder, are parallel to or coincide with a radial line of the arc-shaped rail. The three lines are located on a same plane, which is parallel to or coincide with the plane where the arc-shaped rail is located. The three lines intersect at one point.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a detachable and assembled arc-shaped precise positioning device. Background technique [0002] Minimally invasive spine technology is to reduce the trauma to surrounding tissues as much as possible on the premise of maintaining the curative effect of surgery, so as to achieve small surgical incision, less tissue damage, light systemic reaction, fast recovery period and good psychological effect. At present, the minimally invasive technique of the spine is developing vigorously, and has achieved good practical results and good social benefits in the clinical treatment of spinal diseases. More and more spine surgeons have begun to pay attention to and develop the minimally invasive technique of the spine. However, minimally invasive spinal techniques require precise surgical operations within a limited field of view and must rely on the positioning of imaging equipment. T...
