The guidable incision expander comprises a blade, a handle and a guide sheath core, wherein the blade is connected with the handle, the guide sheath core is arranged above the handle, and the guide sheath core is a hollow circular tube. The portable incision expander is suitable for being used for accurately expanding the incision range of a guide wire implantation point during interventional minimally invasive surgery, wherein the guide sheath core is a hollow circular tube, and when the minimally invasive surgery is intervened, the guide sheath core can be accurately guided to a puncture point through the implanted guide wire, so that the incision of the puncture point is expanded.
Description
Technical Field
The utility model belongs to the technical field of medical equipment, and particularly relates to a guidable incision expander.
Background
When the minimally invasive surgery is intervened (a jugular vein puncture catheter, a percutaneous abdominal cavity catheter, a percutaneous biliary tract puncture catheter and the like), the puncture point range needs to be enlarged after a guide wire enters a blood vessel or a bile duct through a puncture point, so that the guide wire is conveniently fed into a puncture sheath with a thicker diameter and the like, the puncture point is along with blood seepage, the position of the puncture point cannot be accurately judged by the conventional blade, errors and the like possibly exist between the incision of the blade and the puncture point, unnecessary injury of a patient is caused, how to quickly and accurately enlarge the puncture point, the pain of the patient is relieved, the operation difficulty is shortened, and a portable incision expander is needed to accurately position and enlarge the puncture point of the patient.
SUMMERY OF THE UTILITY MODEL
The utility model provides a guidable incision expander to solve the problem that a puncture point cannot be accurately searched and expanded in the process of a minimally invasive surgery of a patient.
In order to achieve the purpose, the technical solution of the utility model is as follows:
a guidable incision expander comprises a blade, a handle and a guide sheath core, wherein the blade is connected with the handle, the guide sheath core is arranged above the handle, and the guide sheath core is a hollow circular tube.
Preferably, the blade is a scalpel blade.
Preferably, the guide sheath core is a conical hollow round tube.
Preferably, the handle includes a connecting portion and a holding portion, the connecting portion is connected with the blade, and the holding portion is flat.
Preferably, the grip portion is provided with a recess.
Preferably, the guide sheath core is integrally connected with the knife handle.
Preferably, the guiding sheath core and the knife handle are made of plastic or metal materials.
The utility model has the beneficial effects that:
the portable incision expander is suitable for being used for accurately expanding the incision range of a guide wire implantation point during interventional minimally invasive surgery, wherein the guide sheath core is a hollow circular tube, and when the minimally invasive surgery is intervened, the guide sheath core can be accurately guided to a puncture point through the implanted guide wire, so that the incision of the puncture point is expanded.

In addition, the descriptions related to "first", "second", etc. in the present invention are only for descriptive purposes and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.
In the present invention, unless otherwise expressly stated or limited, the terms "connected," "secured," and the like are to be construed broadly, and for example, "secured" may be a fixed connection, a removable connection, or an integral part; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
In addition, the technical solutions in the embodiments of the present invention may be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination of technical solutions should not be considered to exist, and is not within the protection scope of the present invention.
Referring to fig. 1, the guidable incision expander comprises a blade 1, a handle 2 and a guiding sheath core 3, wherein the blade 1 is connected with the handle 2, the guiding sheath core 3 is arranged above the handle 2, and the guiding sheath core 3 is a hollow circular tube. The guide sheath core 3 and the knife handle 2 are connected integrally.
The blade 1 is an arc medical blade with a sharp head, so that the wound of a patient is easier to enlarge. The guide sheath core and the knife handle are made of plastic or metal materials, or other materials, and the materials of the guide sheath core and the knife handle are not limited. Guide sheath core 3 sets up in handle of a knife 2 tops, and guide sheath core 3 can pass through the seal wire more fast for hollow pipe, finds the wound position more accurately.
The guide sheath core 3 is a conical hollow round tube, and is beneficial to entering a puncture point. During operation, the puncture point is very small, so that the sharp head enters the puncture point first and then expands slowly.
Further, the tool holder 2 includes a connecting portion 21 and a holding portion 22, the connecting portion 21 is connected to the blade 1, and the holding portion 22 is flat. Preferably, the grip portion is provided with a recess. The concave part is arranged on the holding part at the rear part of the knife handle, so that a doctor can hold the scalpel more comfortably and stably for operation.
The portable incision expander is suitable for being used for accurately expanding the incision range of a guide wire implantation point during interventional minimally invasive surgery, wherein the guide sheath core is a hollow circular tube, and when the minimally invasive surgery is intervened, the guide sheath core can be accurately guided to a puncture point through the implanted guide wire, so that the incision of the puncture point is expanded.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
