Description
Technical Field
The utility model relates to a medical instrument, concretely relates to medical instrument handle.
Background
The medical devices such as catheters are required to be connected with a handle, so that doctors can operate the catheter outside a patient body conveniently in clinical application. The catheter is connected with the handle by generally selecting UV glue and bonding the catheter and the handle through ultraviolet light curing. The base material of the catheter bonding part is generally made of nylon, Pebax and other materials, the surface energy of the materials is low, UV glue is difficult to attach, and the catheter bonding part belongs to the base material difficult to bond; the handle is generally made of polycarbonate, the surface energy is high, the UV glue is easy to adhere, and the handle belongs to a base material which is easy to bond.
Disclosure of Invention
The utility model provides a medical instrument handle.
The technical scheme of the utility model:
a medical device handle, the medical device comprising a catheter, the catheter being connected to the handle; the handle is characterized in that a straight pipe is sleeved at the tail end of the guide pipe, the straight pipe and the guide pipe are coaxial, a gap is reserved between the straight pipe and the guide pipe, UV glue is filled in the gap space, the UV glue is solidified through ultraviolet light, the guide pipe and the straight pipe are connected, and the solidified UV glue and the straight pipe jointly form the handle.
Considering that in the actual production process, due to the fact that glue is converted from a liquid state to a solid state during UV curing, volume shrinkage exists, when UV light is irradiated, the UV glue on one side of the handle is firstly contacted with the light, the UV glue on one side of the conduit is finally contacted with the light, the adhesive force on the UV glue handle is higher than that on the conduit, the glue layer is peeled off from the side of the conduit, and the connection of the handle has a defect rate of 30-40%; further dividing the gap space into an upper part and a lower part, filling UV glue in the upper part, and connecting the upper part of the guide pipe and the upper part of the straight pipe through UV curing of the UV glue; filling UV glue in the lower part, and connecting the lower part of the guide pipe and the lower part of the straight pipe through UV curing of the UV glue; the installation method is as follows;
1) assembly conduit
Inserting a lining core into the straight pipe, wherein the lining core penetrates through the straight pipe; then the lining core is penetrated into the conduit to guide the conduit to the straight conduit so as to ensure the conduit and the straight conduit to be coaxial.
2) First stage curing
Inserting the injector filled with glue into the gap between the guide pipe and the straight pipe, pushing the injector to the lowest end of the guide pipe, injecting the glue to a position half the height of the straight pipe, namely completing the injection of the UV glue of the lower part, pulling out the injector, and irradiating the UV light from top to bottom (the angle is between 15 and 75 degrees) by utilizing an ultraviolet light guide device to cure the UV glue of the lower part, namely curing the UV glue of the first section.
3) Second stage curing
Inserting the injector into the gap between the guide pipe and the straight pipe, pushing the injector to the upper edge of the glue on the lower part, injecting the glue while moving the injector until the glue is full of the straight pipe, namely, completing the injection of the UV glue on the upper part, removing the injector, and then irradiating UV light from bottom to top (the angle is between 15 and 75 degrees) by utilizing an ultraviolet light guide device to cure the UV glue on the upper part, namely, curing the glue on the second section; and finishing the installation of the handle. Dividing UV curing into 2 sections according to the directional shrinkage characteristic of the UV glue; during the first section curing, the UV glue is filled in the space of the half lower part of the handle, the UV light irradiates from top to bottom, the UV glue at the upper part contacts the light firstly, so the UV glue shrinks upwards, and the complete connection of the middle section of the handle is ensured; during the second stage of curing, the UV glue is filled in the left half space of the handle, the UV light irradiates from bottom to top, the UV glue at the lower part of the handle contacts with the light firstly, so the UV glue shrinks downwards, and the UV glue at the upper part of the handle also fills downwards a small space of a product shrunk due to curing under the action of gravity; not only guarantee that the handle middle section is connected intact, also play the reinforcement effect once more, prevent that the glue film from breaking away from.
The utility model has the advantages of, reasonable in design, simple structure improves the yield that the handle is connected by a wide margin.

Detailed Description
As shown in fig. 1-4. A medical instrument handle comprises a catheter 1, wherein the catheter 1 is connected with a handle 2; the tail end of the guide pipe 1 is sleeved with a straight pipe 2-1, the straight pipe 2-1 and the guide pipe 1 are coaxial, a gap is reserved between the straight pipe 2-1 and the guide pipe 1, the gap space is divided into an upper part and a lower part, the upper part is filled with UV glue 2-2, the UV glue 2-2 is cured through ultraviolet light, the upper part of the guide pipe 1 and the upper part of the straight pipe 2-1 are connected, the lower part is filled with UV glue 2-3, the UV glue 2-3 is cured through the ultraviolet light, and the lower part of the guide pipe 1 and the lower part of; the solidified UV glue 2-2 and 2-3 and the straight pipe jointly form the handle 2.
The above disclosure is only for the preferred embodiment of the present invention, but not intended to limit itself, and any changes and modifications made by those skilled in the art without departing from the spirit of the present invention shall fall within the protection scope of the present invention.
