Description

Intelligent hemostatic forceps

Technical Field

The invention relates to the field of medical instruments, in particular to an intelligent hemostatic forceps.

Technical Field

Intelligent hemostats are often required in clinical procedures to prevent excessive blood loss from patients. The current common intelligent hemostatic forceps are hemostatic forceps, such as elbow hemostatic forceps, straight-head hemostatic forceps, oval forceps and the like of local blood vessels. The traditional management mode of the hemostatic forceps as a medical instrument relies on a non-automatic system based on paper documents or paper labels for recording and tracking, and asset management is completely implemented manually, so that the efficiency is low, and the number and the scale of the managed hemostatic forceps are small. With the popularization of computer application, data information managed by medical instrument warehouses of a plurality of hospitals is managed by a computer data system at present, but the data is collected and statistically organized in a mode of firstly recording paper and then manually inputting the paper into a computer. The management of hospital ward medical instruments still stays at present in that clinical medical personnel must check the used and idle medical instruments in a ward before going off work every day, and the main mode of checking is that the clinical medical personnel find each medical instrument and check the medical instrument with a medical equipment list table one by one to complete checking, and fill related records on a medical instrument record book. The traditional data entry method is low in speed and accuracy, and the paper label is easily polluted by the environment. Therefore, the requirement of increasingly refined management of various medical instruments cannot be met, and the operating efficiency of the medical instrument management department in the hospital is influenced.

Electronic tags have emerged in the prior art as a tool for intelligent inventory management. However, these tags are usually based on a dipole form and can only be used for non-conductive materials such as automotive glass, cartons and the like. When the object to be managed is a metal part with a small volume, the object is managed by adopting an external label mode. The defects of the mode are obvious, for example, the external label is easy to be confused by human errors, the reading distance of the external label in a metal environment is sharply reduced, and even the reading fails.

Detailed Description

The technical solution of the present invention is described in detail below with reference to the accompanying drawings and the detailed description.

The first embodiment is as follows:

a first embodiment of the present invention is shown in fig. 1-3. The intelligent hemostatic forceps of this embodiment includes: the clamp comprises a clamp 1, a clamp rod 2, a handle 3, a handle fixing clamp tooth 4 and an electronic tag 5.

One end of the clamp rod 2 is connected with the handle 3, and the other end of the clamp rod 2 is welded with the clamp 1. Handle fixed clamp teeth 4 are welded on the opposite sides of the handle 3 respectively, and the handle fixed clamp teeth 4 are meshed with each other in a matching mode. Preferably, jaw 1 also includes jaw teeth on its occlusal surface. The clamping teeth make the clamped pliers not easy to slip off.

The space formed on the surface of the clamp bar 2 for accommodating the electronic tag 5 and the protective resin 6 is a rectangular parallelepiped. The rectangular parallelepiped forms a portion cut away from the caliper bar 2. The cuboid runs through along two side surfaces perpendicular to the length direction of the clamp rod 2. The upper surface of the rectangular parallelepiped parallel to the second radiation element 52 is an open plane. The lower surface of the rectangular parallelepiped parallel to the second radiation unit 52 is in contact with the bottom surface of the electronic tag 5.

As shown in fig. 2, a space for accommodating the electronic tag 5 and the protective resin 6 is opened on the surface of the clamp lever 2. The electronic tag 5 is disposed in the space. Two ends of the electronic tag 5 along the length direction of the clamp rod 2 are spaced from the inner wall of a space formed by the clamp rod 2 and used for accommodating the electronic tag 5 and the protective resin 6 by a distance h. The upper surface of the protective resin 6 is flush with the surface of the caliper bar 2.

As shown in fig. 3-5, the RFID chip 53 connects the first and second

radiating elements

51 and 52 together. The RFID chip 53 is located in the upper left area of the upper surface of the electronic tag 5. The first slit 54, the second slit 55, and the third slit 56 are sequentially provided on the upper surface of the electronic tag 5 in a direction away from the RFID chip 53. The connection points of the RFID chip 53 and the first and second

radiating elements

51 and 52 can be tuned to the operating frequency of the electronic tag 5.

According to an aspect of the present embodiment, the first slit 54 is disposed at one end of the second radiation unit 52 in the length direction of the caliper bar 2. The open end of the first slit 54 faces the RFID chip 53. The distance of the first slot 54 from the RFID chip 53 enables a significant tuning of the operating frequency of the electronic label 5. The second slit 55 is parallel to the third slit 56. The first slit 54 and the second slit 55 are perpendicular. The first slit 54, the second slit 55, and the third slit 56 tune the radiation element formed by the first radiation element 51 and the second radiation element 52. Optionally, more slots may be provided to tune the electronic tag 5. The first slit 54, the second slit 55, and the third slit 56 are preferably rectangular in shape, and the slit width is preferably 0.1mm to 3 mm.

The first radiating element 51 extends to the lower surface of the electronic tag 5 in a direction away from the RFID chip 53 to form a first ground electrode 510. The second radiating element 52 extends to the lower surface of the electronic tag 5 in a direction away from the RFID chip 53 to form a second ground electrode 511. The first ground electrode 510 and the second ground electrode 511 are coupled to the surface of the caliper bar 2. The first and

second radiation elements

51 and 52 have first and

second coupling electrodes

57 and 59 formed on both end surfaces of the substrate 512. The first coupling electrode 57 and the second coupling electrode 59 are coupled with the inner wall of the space formed by the nipper bars 2, in which the electronic tag 5 and the protective resin 6 are accommodated. Wherein the coupling distance h can be adjusted in size to tune the operating frequency of the electronic tag 5. Preferably, the coupling distance h is 0.5-3 mm. The second radiation element 52 has a tuning electrode 58 formed thereon. The connection point of the tuning electrode 58 to the second radiating element 52 may be located anywhere along the side of the second radiating element 52. The tuning electrode 58 extends to the lower surface of the electronic tag 5 to form a third ground electrode 513. The first ground electrode 510, the second ground electrode 511, and the third ground electrode 513 are coupled to the surface of the clamp lever 2 to ensure good grounding and to tune the operating frequency of the electronic tag 5.

The grounding path of the tuning electrode 58 can be adjusted by changing the length of the first slot 54, and thus the grounding path of the second radiating element 52 can be changed to tune the operating frequency of the electronic tag 5.

The electronic tag 5 utilizes the surface of the clamp rod 2 as a reflector, and the working frequency of the electronic tag 5 is tuned through the coupling capacitance generated by the first coupling electrode 57, the second coupling electrode 59, the clamp rod 2, and the grounding path formed by the first gap 54, the second gap 55, the third gap 56 and the tuning electrode 58. The defect that the electric length of the radiation unit of the electronic tag 5 on the small clamp rod is insufficient is overcome, so that the excellent reading effect can be achieved in a small volume.

The radiating elements and electrodes of the electronic label 5 may be made of commonly used conductive materials, such as gold, silver, copper, or aluminum foils. The radiating elements and electrodes of the electronic tag 5 may also be disposed on the substrate 512 by means of screen printing using conductive ink. Substrate 512 is formed of a dielectric material. Such as plastic, foam, ceramic. The substrate 512 is preferably formed of a ceramic material having a relative dielectric constant of 90-150.

The resin 6 for protection may employ a commonly used thermoplastic resin or thermosetting resin. The upper surface of the protective resin 6 is flush with the surface of the clamp rod 2, so that the smooth surface of the clamp rod 2 can be kept, and the clamp rod is convenient to clean and is not corroded by body fluids such as oil stain, water, blood and the like.

The operating frequency band of the electronic tag 5 may be selected from the microwave frequency band, preferably from the UHF frequency band. The electromagnetic wave can transmit the resin 6 to transmit the information stored in the RFID chip 53 of the electronic tag 5. The RFID chip 53 has unique ID information stored therein, which can be read by a reader for asset management of the hemostat. Under the UHF frequency band, the stable reading distance of the intelligent hemostatic forceps obtained by adopting the RFID reader-writer is about 1.5m, and the requirement of asset management is met.

The above description is only a specific implementation of the embodiments of the present application, but the scope of the embodiments of the present application is not limited thereto, and any person skilled in the art can easily conceive of changes or substitutions within the technical scope of the embodiments of the present application, and all the changes or substitutions should be covered by the scope of the embodiments of the present application. Therefore, the protection scope of the embodiments of the present application shall be subject to the protection scope of the claims.
