Description
Technical Field
The utility model relates to a backbone scope auxiliary device field of medical instrument especially relates to a work sleeve pipe that cooperation backbone scope used.
Background
With the aging of the population of China, the number of the people suffering from the spinal degenerative diseases and the incidence rate of the spinal degenerative diseases are in a continuously increasing trend. Conservative treatment and surgical treatment can be adopted for treating the disease at present. Some patients may experience some relief from conservative treatment, while some patients may be less effective and surgical treatment is another option for treating these conditions. With the progress and development of medical technology and surgical technology, the spine surgery has been developed dramatically, the spine surgery of today is quite different from the traditional spine surgery in the past, and the spine surgery has unconsciously entered the spine minimally invasive age. The spine endoscopic surgery is to use a small incision to puncture to reach the diseased part, establish a working channel by means of a blunt dilating cannula, accurately treat the diseased part and solve the disease of a patient.
With the improvement and development of the spinal endoscope technology, some problems are found in clinical application: 1. the existing working sleeve is mainly kept stable by the contraction force of the muscle of a patient and the holding of an operator after puncturing, expanding and forming a working channel, but for a heavier patient with narrow spinal canal, the number of places to be treated in the operation is more, the time is longer, the contraction force of the muscle around the sleeve of the patient is weaker and weaker, the operator holds the wrist and the arm of the working sleeve system of the spinal endoscope for a long time, and the wrist and the arm are uncomfortable, so that the operation can be influenced, and sometimes even the phenomenon that the working sleeve falls off in a small range can occur. 2. Under-the-scope trepan or bone drill are often used for processing in spinal endoscopic surgery, and when processing target tissues around nerve roots and spinal cords, an operator considers the safety of the surgery and needs to limit the depth of a spinal endoscopic system. Currently, depth-limiting devices are used on the rods of individual instruments such as trephines, bone drills and bone files, and each instrument needs to be adjusted to limit the depth before being placed into a working cannula, so that the operation increases the operation workload of surgical assistants. 3. The spinal endoscope system working sleeve pipe that uses at present is the fixed length, though divide into 3 grades according to length, is applicable to different spinal column sections and different crowds, but to different fat and thin patients, because fine setting can not be accomplished to current working sleeve pipe, sometimes also can bring the inconvenience of operation.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.
As shown in figure 1 ~ 4, the working cannula used with the spinal endoscope comprises a body 1, a depth-limiting barrel 2 and an extension barrel 3, and the technical scheme is that the body 1 comprises an inner barrel 101, an outer barrel 102 coaxially arranged outside the inner barrel 101 and an annular plate 103 arranged between the inner barrel 101 and the outer barrel 102 and used for connecting the inner barrel 101 and the outer barrel 102, external threads are arranged on the outer side wall of the inner barrel 101, internal threads corresponding to the external threads of the inner barrel 101 are arranged on the inner side wall of the depth-limiting barrel 2, the extension barrel 3 is arranged in a surgical incision, the working cannula is prevented from sliding into the surgical incision due to weakened muscle tension through the body 1 with a larger diameter arranged outside the surgical incision, and the defects in the prior art are overcome.
Meanwhile, in order to prevent the problem that the depth of screwing-in of the depth-limiting cylinder 2 is too large to cause the problem that the depth cannot be taken out when the depth-limiting cylinder is screwed off to be close to the body 1, a horizontal fixing plate 1A is arranged on the side wall of one end of the inner cylinder 101, which is far away from the extension cylinder 3; a horizontal fixed seat 3A is arranged on the side wall of one end of the outer cylinder 102 far away from the extension cylinder 3; a cavity 30 with an opening at the top is arranged in the horizontal fixing seat 3A; a triangular spring plate 31 is arranged in the cavity 30; the bottom edge of the triangular elastic sheet 31 is contacted with the bottom of the cavity 30, and the vertex angle of the triangular elastic sheet 31 protrudes out of the plane of the horizontal fixed seat 3A towards the horizontal fixed plate 1A through the opening of the cavity; a groove 10 corresponding to the protruding part of the triangular elastic sheet 31 is formed in the plane of the horizontal fixing plate 1A facing the horizontal fixing seat 3A; the grooves 10 extend in a direction perpendicular to the axis of the inner cylinder 101.
Similarly, the outer cylinder 102 may be a rotary body having an L-shaped cross section, and may be coaxially disposed outside the inner cylinder 101, to have a configuration as shown in fig. 1.
As shown in fig. 2, since the depth-limiting cylinder 2 is connected to the inner cylinder 101 through a thread, in order to prevent the looseness between the horizontal fixing seat 3A and the horizontal fixing plate 1A, two or three or more grooves 10 may be provided in the horizontal fixing plate 1A for cooperating with the triangular spring plate 31. Taking three grooves 10 as an example, when the triangular elastic piece 31 contacts the horizontal fixing plate 1A, because the depth limiting cylinder 2 is screwed downwards, the triangular elastic piece 31 is deformed, the depth limiting cylinder 2 drives the horizontal fixing plate 1A to only be screwed downwards, when the triangular elastic piece contacts the groove 10, the medical staff can not screw any more, and the vertex angle of the triangular elastic piece 31 enters the nearest groove 10, so that the limiting structure is formed. However, if the medical staff is not relieved, the medical staff may worry about the situation of the limit being not tight, and the medical staff can continue to screw, and when the medical staff reaches the adjacent second groove 10, the limit force between the triangular spring plate 31 and the groove 10 is strengthened. If not reassuring, it can be screwed again until a third groove 10 of maximum restraining force is reached.
Aiming at special patients, such as obese patients, the fat of the patients is thick, and the inner side wall of the inner cylinder 101 is provided with internal threads; the outer side wall of the extension cylinder 3 is provided with an external thread corresponding to the internal thread of the inner cylinder 101, so that the extension cylinder 3 can be vertically moved on the inner side wall of the inner cylinder 101, and the visual field adjustment operation in the operation is facilitated.
It is to be understood that: as shown in fig. 5, the outside of the depth stop 2 may be provided with a scale as required to express the raised height of the depth stop 2.
It is to be understood that: the triangular spring 31 can be made of phosphor bronze, tin bronze, 65mn, 55Si2Mn, 60Si2MnA, 55 simmnvb, 55 simmnmov, 60CrMn, 60CrMnB, 302, 316 and other brands of flat steel strips.
The foregoing is considered as illustrative and not restrictive, and all changes that come within the spirit and principles of the invention and any equivalents thereto are intended to be embraced therein.
