Abstract
The utility model provides a centrum fracture minimal access surgery percutaneous puncture cannula device comprises puncture cannula and nook closing member, puncture cannula comprises cavity sleeve pipe and base, the middle part and the cavity sleeve pipe intercommunication of base one side, and the opposite side is the opening, and opening one side is provided with the recess, the nook closing member is anterior to be the pjncture needle, and the tail end is the handle, and the handle inboard is provided with the arch. The pjncture needle external diameter is less than cavity sheathed tube internal diameter, in using, it is intraductal that the pjncture needle penetrates the cavity cover, inlays arch on hand in the recess on the puncture cannula base. The front end of pjncture needle is the slope, and after the pjncture needle penetrated the cavity sleeve pipe, cavity cover outside of tubes was stretched out on its front end slope. The utility model discloses inlay arch on hand in the recess on the puncture cannula base, adopt sleeve pipe and nook closing member fixed connection structure, strengthened percutaneous pjncture needle maneuverability to it is more simple feasible to make the operation. The utility model discloses simple manufacture does benefit to the operation, can cooperate multiple apparatus to perform the operation, can satisfy clinical demand.
Description
Technical field
This utility model belongs to the apparatus setting up Minimally Invasive Surgery service aisle, is specifically related to the percutaneous puncture casing bit for vertebral fracture, aseptic necrosis of femoral head minimal invasive operation.
Background technology
Treatment vertebral fracture and aseptic necrosis of femoral head, currently mainly contains three kinds of Therapeutic Method: traditional conservative therapy, the treatment of conventional surgical open surgery and minimal invasive operation.With other two kinds of Measures compare, minimal invasive operation treatment time is short, and wound is little, and pain is little, and recovery time is short and the hospital stays is short, is thus widely used gradually and will becomes following main flow Therapeutic Method.
Minimal invasive operation be by puncture instrument puncture enter diseased region, then by perfusion or drain to change diseased region mechanical strength or to alleviate internal pressure, reach fast pain relief, improve the object of life quality.
Existing a kind of percutaneous vertbroplasty complete surgical instruments, its structure is made up of vertebral body puncture casing and nook closing member, and nook closing member is enclosed within sleeve pipe, and nook closing member can rotate freely in sleeve pipe, without fixed structure; In use, because nook closing member rotates freely in sleeve pipe, just there is the risk that nook closing member drops out from sleeve pipe in this apparatus, thus operability is not strong, operation risk is larger.
Utility model content
This utility model object is to provide one to treat the Minimally Invasive Surgery such as vertebral fracture, aseptic necrosis of femoral head percutaneous puncture casing bit, manufactures a kind of percutaneous puncture device meeting biological engineering mechanics.Thus be beneficial to the operating theater instruments of the minimal invasive operation such as vertebral fracture, aseptic necrosis of femoral head, promote completing smoothly of operation.
A kind of vertebral fracture percutaneous puncture casing bit, is characterized in that, be made up of puncture casing and nook closing member;
Described puncture casing is made up of hollow sleeve and base, and the middle part of base side is communicated with hollow sleeve, and opposite side is opening, and opening side is provided with groove;
Described puncture needle external diameter is less than the internal diameter of described hollow sleeve; During use, described puncture needle penetrates in hollow sleeve, and the projection on handle is embedded in the groove on described puncture casing base.
The front end of described puncture needle is slope, and after puncture needle penetrates hollow sleeve, its slope, front end is stretched out outside hollow sleeve.
Described percutaneous puncture sleeve pipe and nook closing member are made up of medical steel, and wherein, described base and nook closing member tail end fixture are made up of resin material or plastics.
When this utility model operation uses, under image documentation equipment monitors, this utility model puncture is entered according to the scheme designed in advance and hinder in vertebra or femoral head, withdraw from nook closing member and retain sleeve pipe, surgical work passage can be formed.
This utility model solves prior art Problems existing, and the projection on handle is embedded in the groove on described puncture casing base, have employed sleeve pipe and nook closing member fixed connection structure, enhances percutaneous needle operability, thus makes operation more simple possible.This utility model makes simple, is beneficial to operation, multiple apparatus can be coordinated to perform the operation, can meet clinical demand.

1 puncture casing, 11 hollow sleeves, 12 bases, 13 grooves,
2 nook closing members, 21 puncture needles, 22 handles, 23 boss, 24 slopes.
Detailed description of the invention
Preferred embodiment accompanying drawings of the present utility model is as follows:
A kind of vertebral fracture percutaneous puncture casing bit, is made up of puncture casing 1 and nook closing member 2;
Described puncture casing is made up of hollow sleeve 11 and base 12, and the middle part of base side is communicated with hollow sleeve, and opposite side is opening, and opening side is provided with groove 13;
Described nook closing member front portion is puncture needle 21, and tail end is handle 22, is provided with protruding 23 inside handle.
Described puncture needle external diameter is less than the internal diameter of described hollow sleeve; During use, described puncture needle penetrates in hollow sleeve, and the projection 23 on handle is embedded in the groove 13 on described puncture casing base.
The front end of described puncture needle is slope 24, and after puncture needle penetrates hollow sleeve, its slope, front end is stretched out outside hollow sleeve.
