Description

Visual trepan for intervertebral foramen mirror

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a visual trepan for intervertebral foramen mirror.

Background

The prolapse of intervertebral disc is the main cause causing many patients' back pain, "foramin mirror technique" because its wound is little, resume fast and the low grade characteristic of expense, often treat prolapse of intervertebral disc with this technique, "foramin mirror technique" under the mirror visible working environment is especially important for the trepan operation process, can avoid or excise the bony tissue that blocks the cannula effectively and can monitor the specific situation of operation position in real time, etc. all influence the security that the trepan used to different extents.

In order to solve the problems, Chinese patent (patent publication No. CN208677503U) discloses an under-mirror visible trepan, which comprises a tubular saw body, wherein one end of the tubular saw body is provided with saw teeth, the other end of the tubular saw body is provided with a handle, the middle part of the tubular saw body is hollow, the handle is provided with a through hole communicated with the hollow part, the under-mirror visible trepan further comprises an endoscope, and a probe of the endoscope penetrates into the hollow part of the tubular saw body through the through hole on the handle.

According to the scheme, the probe of the endoscope penetrates into the hollow part of the tubular saw body from the through hole, the operation environment is placed under a visible condition, and the safety of the operation is improved; however, the scale of the visible trepan of the device is arranged on the outer side of the pipeline, and the depth of the trepan entering intervertebral bone cannot be directly observed in the actual operation process, so that potential safety hazards are caused, and therefore the visible trepan with the scale engraved on the inner side of the trepan is needed.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a visual trepan for intervertebral foramen mirror to solve prior art's trepan scale and carve the system in the outside, lead to the security problem that the unable direct observation trepan got into the degree of depth of intervertebral sclerotin and brought in the operation in-process.

In order to achieve the above object, the present invention provides the following technical solutions:

the utility model provides a basic technical scheme is: the utility model provides a visual trepan for intervertebral foramen mirror, includes sleeve pipe, trepan and endoscope subassembly, bushing connection has the handrail, the trepan wears to locate the sleeve pipe, the one end of trepan is connected with the twist grip, the other end of trepan is equipped with the sawtooth, the inner wall of trepan has carved with interior scale mark, endoscope subassembly includes electronic display screen and optical lens, optical lens is used for observing interior scale mark.

The principle of the basic technical scheme is as follows: in the operation process, the sleeve pipe outwards expands the soft tissue, and the handrail of handheld sleeve pipe is convenient for fixed to the sleeve pipe, and in the trepan worn to locate the sleeve pipe, rotate the sawtooth that the twist saw drove the trepan and carry out the operation, the sclerotin that saw cut off etc. entered into the trepan intraductally, optical lens observed the position display that sclerotin on the inner scale mark on electronic display screen, obtained the depth that the trepan entered intervertebral sclerotin.

The beneficial effects of the basic technical scheme are as follows: the setting is more convenient than the scale mark of current trepan outer wall at the inboard interior scale mark of trepan and is observed, and the data that show on the electronic display screen are accurate, and the image of sclerotin changes in the intercepting or recording trepan, and the medical personnel of being convenient for guarantee to improve the degree of depth that the single saw cut when avoiding sawing the excess to the judgement of operation process, and operation efficiency and factor of safety are high.

Preferably, the outer wall of one end of the rotating handle of the trepan is carved with outer scale marks, the outer wall of the trepan is rotatably connected with an adjusting sleeve, the outer diameter of the adjusting sleeve is larger than the inner diameter of the sleeve, and the adjusting sleeve moves axially along the trepan.

Through the arrangement, the single entering range of the trepan is adjusted by the adjusting sleeve, the range of the trepan is adjusted according to the actual operation requirement, the depth of the trepan entering intervertebral bone is smaller than or equal to the range of the trepan, and the phenomenon that the trepan is cut excessively due to operation errors or observation errors is avoided.

Preferably, the handrail is T-shaped, and the rotating handle is a ball cake-shaped handle.

Through the arrangement, the T-shaped handrail is convenient to hold by a hand and fix the sleeve, the spherical cake-shaped rotating handle is completely attached to the palm of a person, and the circular saw is accurately controlled to rotate and cut off conveniently.

Preferably, the cake-shaped rotating handle is integrally formed with a protrusion.

Through the arrangement, the friction force of the rotating handle is increased by the mode of being provided with the protrusions, the rotating handle is not easy to slip, and meanwhile, the ring saw is convenient to disinfect.
