Description
Technical Field
The utility model relates to the field of medical equipment, specifically a novel puncture ware core.
Background
With the development of medical technology, medical puncture outfits are more and more widely applied, are suitable for minimally invasive procedures of abdomen, chest and obstetrics and gynecology, provide a passage for the entry of endoscopic instruments, and can provide CO2 gas during the operation.
With the development of the medical market, the competition of medical instruments has been very intense, and the experience of patients and the operational convenience of doctors have become competitive treasures of small and medium-sized medical instrument companies while satisfying the basic functions. However, most of the existing puncture outfits for laparoscopes in the domestic market use the scheme of the traditional factory on the design of the puncture core, but the feeling of the patient and the use of the instruments are not considered too much by the scheme of the factory, and most of the puncture outfits can achieve the functional purpose. Because the operator mostly carries the rubber gloves, the friction is small, and the hidden trouble that the operation stability of a doctor is influenced is caused.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is to overcome the defects of the prior art, and the novel puncture device core is provided, wherein the end rod head is improved, the inner layer hard shell is used for supporting, the strength of the puncture device core is kept, the hollow structure can effectively reduce the material consumption, and the production cost is reduced; the friction coefficient is improved by utilizing the external anti-slip layer, and the operation stability is enhanced; the anti-skid bumps are used for positioning the hands, so that the operation stability of the puncture outfit is further improved.
In order to achieve the above purpose, the utility model adopts the technical scheme that: a novel puncture core comprises a core rod and an end rod head arranged at the upper end of the core rod; the end part rod head is of a hollow structure and comprises an inner hard shell and an outer anti-slip layer coated on the inner hard shell; the end part rod head is symmetrically provided with a closed button, wherein the upper end of the closed button is provided with an anti-skid bulge.
The outer anti-skid layer is an elastic rubber layer, and the thickness of the outer anti-skid layer is more than or equal to 3 mm; the surface of the elastic rubber layer is provided with anti-skid particles, and the particle size of the anti-skid particles is 0.5 mm-0.8 mm.
The anti-skid bulges are convex arc-shaped bodies, and the height of the anti-skid bulges is 3-5 mm.
The front end of the core rod is a puncture conical head.
The closed button is hinged on the inner layer hard shell.
Because of above-mentioned technical scheme's application, compared with the prior art, the utility model have the following advantage:
the end rod head is improved, the inner layer hard shell is used for supporting, the strength of the puncture core is kept, the hollow structure can effectively reduce the material consumption, and the production cost is reduced; the friction coefficient is improved by utilizing the external anti-slip layer, and the operation stability is enhanced; the anti-skid bumps are used for positioning the hands, so that the operation stability of the puncture outfit is further improved.
Drawings
The technical scheme of the utility model is further explained by combining the attached drawings as follows:
FIG. 1 is a schematic diagram of the appearance structure of the utility model;
FIG. 2 is a schematic diagram of a partial cross-sectional structure of the present invention;
FIG. 3 is a schematic diagram of a partial cross-sectional structure of the present invention;
fig. 4 is a partial structural schematic diagram of the present invention.
In the figure: 1. an outer non-slip layer; 1-1, anti-skid particles; 2. closing the buckle; 3. a core bar; 4. a puncture conical head; 5. an inner hard shell; 6. a linker; 7. and (4) anti-skid bulges.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The novel puncture outfit core shown in fig. 1 to 4 comprises a core bar 3 and an end rod head arranged at the upper end of the core bar 3; when in use, the hand holds the end rod head to insert the puncture outfit core into the puncture cannula, and then the puncture outfit core and the puncture outfit core are inserted into the human body together. In order to prevent the phenomena of poor operation stability, labor waste and the like caused by the slippage of the hand in the operation process, the end rod head of the puncture core is improved into an anti-skidding form, and meanwhile, the sealing buckle 2 has a locking function. The sealing buckle 2 can be matched with a corresponding mechanism on the puncture cannula to lock the puncture core assembled in place with the puncture cannula. The closed button 2 is hinged, the front end of the closed button is provided with a bulge similar to the connecting piece of the happy button, and the connecting principle of the closed button is the same as that of the connecting piece of the happy button.
In order to achieve the purpose, the end part club head is of a hollow structure and comprises an inner hard shell 5 and an outer anti-slip layer 1 coated on the inner hard shell 5; the end part rod heads are symmetrically provided with closed buckles 2, wherein the upper ends of the closed buckles 2 are provided with anti-skid bulges 7. The anti-skid bumps 7 are upward convex arc-shaped bodies, are 3-5 mm high, are matched with the tiger mouths of hands, improve the use experience of holding the end part rod head by hands, are better anti-skid, have the function of positioning the hands, and prevent the hands from sliding downwards along the end part rod head during operation.
The outer anti-slip layer 1 is an elastic rubber layer, and the thickness of the outer anti-slip layer is more than or equal to 3 mm; the surface of the elastic rubber layer 1 is provided with anti-skid particles 1-1, and the particle size of the anti-skid particles 1-1 is 0.5 mm-0.8 mm. The antiskid particles 1-1 are hemispherical rubber particles.
The front end of the core rod 3 is a puncture conical head 4, and the puncture conical head 4 is matched with the outlet of the puncture sleeve.
The closed button 2 is hinged on the inner hard shell 5.
One end of the core bar 3 is directly connected to the inner layer hard shell 5; the core rod 3 is also provided with a connecting body 6, and the connecting body 6 is uniformly distributed between the core rod 3 and the inner hard shell 5, so that the connecting strength between the core rod 3 and the inner hard shell 5 is increased.
The above is only a specific application example of the present invention, and does not constitute any limitation to the protection scope of the present invention. All the technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the present invention.
