Abstract
The utility model relates to a medical appliance, particularly an improvement on structures such as an intervertebral disk mirror with a mirror sheath cam locking mechanism, etc. The utility model primarily solves the technical problems that an endoscopic tube can not be fixed in the prior art, or the endoscopic tube can not do axial movement after fixed so that people can not well observe operation positions, etc. The utility model comprises a mirror body (1) and a mirror tube (2) connected to the mirror body (1); the utility model is characterized in that a U-shaped sheath body (3) is arranged on the mirror body (1); an intervertebral disk mirror (4) is sheathed in the sheath body (3); a pair of locking blocks (3-1) are arranged at the upper end of the sheath body (3); a gap exists between the locking blocks on which clamping mechanisms are arranged.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially relates to a kind of isostructural improvement of MED to band mirror sheath cam lock holding mechanism.
Background technology
Straight formula micro-endoscopic discectomy of the prior art mainly is made up of inside and outside mirror pipe, object lens, prism, mirror body, fiber cable joint, eye end connecting tube, eyepiece system, eyepiece hood and eye end protect tab.Chinese patent discloses a kind of intervertebral disc operation endoscope (CN 2442630Y), and it is realized by following technical measures.Mainly include optical fiber interface, camera interface and sight glass pipe and optical fiber tube on microscope base and the microscope base, its optical fiber tube has two, the axis of the axis of two optical fiber tubes and sight glass pipe is parallel to each other and in same plane, two optical fiber tubes are distributed in the both sides of sight glass pipe, and the outer wall of optical fiber tube is fixedlyed connected with the outer wall of sight glass pipe.The hanging of optical fiber tube and sight glass pipe, the angle that has equal angular on its top.But the mirror pipe of the endoscope of this structure can't be fixed, or can't rotate and axially-movable after fixing, thereby can't observe operative site in all directions.
Summary of the invention
The purpose of this utility model provides a kind of MED with mirror sheath cam lock holding mechanism, it mainly is that the mirror pipe that solves existing in prior technology endoscope can't be fixed, or can't rotate and axially-movable after fixing, thereby the technical problem that can't observe operative site etc. in all directions.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The MED of band mirror sheath cam lock holding mechanism of the present utility model, comprise the mirror body, be connected with the mirror pipe on the mirror body, it is characterized in that described mirror body is provided with U type sheath body, be installed with MED in the sheath body, sheath body upper end is provided with a pair of latch segment, and is gapped between the latch segment, and latch segment is provided with clamp mechanism.Latch segment cooperates the diameter that can finely tune the sheath body with clamp mechanism, thereby can regulate MED at intravital angle of sheath and axial location.
As preferably, described clamp mechanism is: the bolt pair that wears between clip that latch segment is provided with or the latch segment.Clip can directly be clamped paired latch segment; Bolt is secondary to be threaded with latch segment, can be by twisting the spacing between the bolt adjusting latch segment.
As preferably, described clamp mechanism is: be installed with between the latch segment and can lock connecting rod, the latch segment end is connected with cam handle by bearing pin, and cam handle withstands on the latch segment end.Regulate the width in slit by cam handle, thereby regulate the width of sheath body.
Therefore, the utlity model has and to make the locking of mirror body and sheath body more quick and reliable, characteristics such as can regulating of endoscope rotated and axially-movable, thereby can observe operative site in all directions, and be rational in infrastructure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is a kind of right TV structure sketch maps of Fig. 1.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the MED of the band mirror sheath cam lock holding mechanism of this example, as Fig. 1, Fig. 2, a mirror body 1 is arranged, mirror body 1 is provided with mirror pipe 2 and U type sheath body 3, is installed with MED 4 in the sheath body 3, and MED 4 passes sheath body 3 with mirror pipe 2.Sheath body upper end is provided with symmetric a pair of latch segment 3-1, is provided with the slit between the latch segment.Be installed with locking connecting rod 5 in the latch segment, the latch segment end is connected with cam handle 7 by bearing pin 6, and cam handle withstands on latch segment 3-1 end.
During use, sheath body 3 shanks are installed on the snakelike support or hydraulic support of operation table.MED 4 is packed in the sheath body, to be in sheath external with MED 1 fixed locking device, cam handle 7 is connected with locking connecting rod 5 by bearing pin 6, the end face of cam handle 7 pushes against the outer end of latch segment 3-1, move cam handle, the working size that pushes against the part cam handle produce to be changed, thereby position dimension between the two latch segment 3-1 is reduced or increase, reach the relative fixed between MED 4 and the sheath body 3 or separate.Simultaneously, MED 4 can be done rotation on sheath body 3 or axial trace moves, so that observe operative site in all directions.
Claims (3)
1. MED with mirror sheath cam lock holding mechanism, comprise mirror body (1), be connected with mirror pipe (2) on the mirror body, it is characterized in that described mirror body (1) is provided with U type sheath body (3), be installed with MED (4) in the sheath body (3), sheath body (3) upper end is provided with a pair of latch segment (3-1), and is gapped between the latch segment, and latch segment is provided with clamp mechanism.
