Abstract
This patent discloses a kind of tumor micro-wounds to intervene scalpel, belongs to the field of medical instrument technology, including knife handle and cutter head, the knife handle is shell structure, screw rod is provided in the knife handle, the end of the screw rod is fixed with guidance needle, which stretches out from the top of cutter head；Thumb wheel is provided in the knife handle, the outer rim of the thumb wheel is stretched out from the outer wall of knife handle, and latch is provided on the thumb wheel, and the latch is arranged in the helicla flute of screw rod.The utility model is accurately positioned using guidance for surgery location, then directly implement tumor micro-wound intervention operation under the limit of guidance needle, to solve the problems, such as it is of the existing technology be difficult to be accurately positioned and accurately implement operation, the difficulty for effectively reducing tumor micro-wound intervention operation, improves the safety of operation.
Description
Technical field
The utility model relates to medical equipment technical fields, particularly relate to a kind of tumor micro-wound intervention scalpel.
Background technique
Minimally Interventional Therapy, is the emerging therapeutic method between surgery, medical treatment, including intravascular intervention and non-
Vascular interventional treatment.By development in more than 30 years, it is known as three big pillar subjects together with surgery, internal medicine now.Simply
Say, interventional therapy be exactly make several millimeters of diameter of minim channel on blood vessel, skin in the case where not operating on exposed lesion, or
Through the original pipeline of human body, the method for the smallest treatment of wound that lesion is locally treated under the guidance of image documentation equipment.
When clinically to patient implementing tumor micro-wound interventional therapy again, also have to the scalpel for implementing operation many specific
Detail.In general, tumor operation needs first position surgery location, then scalpel are recycled to implement operation,
But existing positioning tool and operation implementation tool be it is distinct, when doctor implement perform the operation when, once experience is insufficient,
It is easy to appear position deviations, even if veteran doctor, it is also possible to because personal reason causes operation out of position.
For example long-term surgery, mental fatigue can not be concentrated on, causing surgery location is not sufferer position.Once as occurring
Situation, it will cause additional pain to patient, while can also bring many troubles to operation.
Summary of the invention
To make up the deficiencies in the prior art, the utility model provides a kind of tumor micro-wound intervention scalpel.
The utility model is achieved by the following technical solution:
A kind of tumor micro-wound intervention scalpel, including knife handle and cutter head, the knife handle are shell structure, are set in the knife handle
It is equipped with screw rod, the end of the screw rod is fixed with guidance needle, which stretches out from the top of cutter head；It is provided in the knife handle
The outer rim of thumb wheel, the thumb wheel is stretched out from the outer wall of knife handle, and latch is provided on the thumb wheel, and the latch is arranged in screw rod
Helicla flute in.
The utility model guides needle and scalpel to realize and match by making, to make tentatively to be oriented to, positioning, puncture
Implement to form whole set of system with operation, the smooth implementation for tumor micro-wound intervention operation provides a great convenience.
Further improvement of the utility model is:
Preferably, axle sleeve frame is fixed with inside the knife handle, the axle sleeve in axle sleeve frame and screw rod cooperate.
Preferably, graduated scale is provided on the cutter head.
Preferably, anti-skid bulge is provided on the knife handle.
Preferably, through-hole is offered on the outer wall of the knife handle, the thumb wheel is stretched out out of this through-hole.
The utility model is accurately positioned using guidance for surgery location, then real directly under the limit of guidance needle
Apply tumor micro-wound intervention operation, thus efficiently solve it is of the existing technology be difficult to be accurately positioned and accurately implement operation ask
Topic effectively reduces the difficulty of tumor micro-wound intervention operation, improves the safety of operation.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the sectional view of the utility model Fig. 1.
Fig. 3 is the partial enlarged view of A.
In figure, 1 screw rod, 2 thumb wheels, 3 guidance needles, 4 latches, 5 helicla flutes, 6 axle sleeve framves, 7 cutter heads, 8 knife handles, 9 anti-skid bulges,
10 through-holes.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
Attached drawing is the embodiments of the present invention, a kind of tumor micro-wound intervention scalpel, including knife handle 8 and cutter head 7, described
Knife handle 8 is shell structure, and screw rod 1 is provided in the knife handle 8, and the end of the screw rod 1 is fixed with guidance needle 3, the guidance needle 3
It is stretched out from the top of cutter head 7；Thumb wheel 2 is provided in the knife handle 8, the outer rim of the thumb wheel 2 is stretched out from the outer wall of knife handle 8,
Latch 4 is provided on the thumb wheel 2, the latch 4 is arranged in the helicla flute 5 of screw rod 1.
Axle sleeve frame 6 is fixed with inside the knife handle 8, the axle sleeve in the axle sleeve frame 6 and screw rod 1 cooperate, on the cutter head 7
It is provided with graduated scale, anti-skid bulge 9 is provided on the knife handle 8, offers through-hole 10 on the outer wall of the knife handle 8, described group
Wheel 2 is stretched out out of this through-hole 10.
In use, stirring thumb wheel 2, screw rod 1 advances in the propulsion of latch 4, and then guidance needle 3 is pushed to advance, this propulsion
Mode is more advantageous to doctor and holds the propulsion progress of guidance needle 3, to efficiently solve of the existing technology be difficult to accurately calmly
Position and accurate the problem of implementing operation, the difficulty of tumor micro-wound intervention operation is effectively reduced, the safety of operation is improved.
