Description

Improved visualizer

Technical Field

The utility model belongs to the field of medical appliances, and particularly relates to an improved visualizer.

Background

The visual medical instrument realizes the visual function of the laryngeal mask medical instrument by matching the endoscope with the medical instrument, and the endoscope is needed to be held in the hand during matching, so that the camera at the front end of the visual medical instrument is ensured to be closely attached to the laryngeal mask observation window at any time, and the image stability is ensured; for example, a visual laryngeal mask has a viewing lumen with a viewing window formed at the distal end and an insertion port formed at the proximal end, and in use, an endoscope is required to be inserted into the viewing lumen, however the entire viewing procedure requires a physician to hold the endoscope, which is inconvenient to operate; and the endoscope is easy to shift, and the visual process is unstable.

Because the visual cavity of the visual laryngeal mask is an arc-shaped extension channel, the whole existing visual device inserting part is a bendable flexible part, and therefore, the inserting part can lack support and other problems in the inserting process, and the inserting process is not smooth.

Example 1

Referring to fig. 1-5, the present utility model provides an improved visualizer 1 adapted for visualizing a visualization channel of a laryngeal mask, which extends in an arc shape as it corresponds to an oral cavity portion of a human body, and which correspondingly has an arc-shaped curved section and a vertical section forming a proximal side of the arc-shaped curved section, the visualizer comprising a handle 2, an insertion portion 3, a camera assembly 5 and a communication connection line 6; the inside of the handle 2 is provided with a threading hole 21, the insertion part 3 at least comprises a hard section and a flexible section from the proximal end to the distal end, the hard section is connected with the handle 2, and the extension length of the flexible section is set to allow the insertion part to be inserted into a visual channel extending in an arc shape; namely, the set length of the flexible channel is at least longer than the length of the arc-shaped bending section of the visual channel, namely, the flexible channel can be inserted into the visual channel, otherwise, the flexible channel is difficult to insert into the visual channel; the insertion portion 3 defines a guidewire channel 300 extending distally from the proximal end; the camera shooting assembly 5 is arranged at the distal end of the insertion part 3; a first end of the communication connection line 6 is used for communication connection with an external device, and illustratively, the first end is provided with a Typ-C connector 61 for connection with a display; the second end of the cable passes through the threading hole 21 and the wire guide channel 300 and is in communication connection with the camera assembly 5.

As such, the visualizer provided by the present embodiments adapts, on the one hand, to the arcuate channel of a visualising medical device such as a laryngeal mask; in addition, the rigid section is used as a supporting guide section, so that the process of placing the visual channel in the visual insertion part 3 is smoother, and the visual observation is more stable.

In some embodiments, the insertion portion 3 further includes a transition section formed between the rigid section and the flexible section, so as to avoid the problem that the insertion portion is easily broken due to direct connection of the rigid section and the flexible section.

In this embodiment, the insertion portion 3 includes a rigid tube 31 and a flexible tube 32 disposed outside the rigid tube, and the distal tube wall of the rigid tube 31 forms a spiral cutting groove 311 to realize the bendable function of the insertion portion, that is, the distal side of the rigid tube 31 has a specific bendable property due to the design of the spiral cutting groove, while the proximal side 310 remains hard.

Further preferably, the helical cutting flutes taper from the proximal end toward the distal end such that the segmented density design achieves a gradual transition from stiff to flexible while the helical cutting flutes achieve a flexible bending characteristic. So as to realize the design of the rigid section, the transition section and the flexible section.

It will be appreciated that the flexible tube retains the proximal flexible distal stiff characteristics of the stiff tube; the spiral cutting groove is provided with a sharp notch, so that the spiral cutting groove can cut an outer tube of the plastic part in the bending and inserting process. Based on this, in some preferred embodiments, the flexible tube 32 includes a braided spiral tube 321 sleeved outside the rigid tube and an outer tube body 322 sleeved on the braided spiral tube, and the outer tube body 322 is made of plastic material, so that the braided spiral tube 321 realizes the bending protection of the cutting spiral groove and prevents the cutting spiral notch from damaging the outer tube body 322 during the laryngeal mask placement process; specifically, the braided spiral tube 321 is a spiral braided net with a layer of material 304 and a braiding density of 60 braided on the outer surface of the rigid tube 31.

The hard pipe is fixedly arranged with the handle; optionally, the handle 2 includes a handle upper cover 211 and a handle lower cover 212, the handle lower cover 3 and the handle upper cover 4 are manufactured by machining, the rigid tube 31 is made of 304 material, and the surface of the rigid tube is provided with a set screw assembly hole 801; the set screw assembly hole 801 is used for aligning with the handle upper cover 4 and simultaneously enabling the two to be assembled and fixed through the set screw 7.

The spiral cut groove 802 is designed to have a groove width of 0.03mm, beginning at a position a certain length from the set screw fitting hole 801. From sparse to dense, the spiral pitch is uniformly reduced from the maximum pitch of 7.4+/-0.5 mm to the minimum pitch of 1.5+/-0.5 mm, and laser cutting is carried out, so that a bendable telescopic hard tube from a handle end to a camera end from hard to soft is obtained, and the effect that the visual device is more smooth and convenient in the bending process of the laryngeal mask is realized;

the hard pipe and the spiral braided pipe are made of metal materials, and the outer pipe body is made of an environment-friendly plastic piece; specifically, the rigid tube 31 and the spiral braided tube 321 are made of 304 materials.

In some examples, the communication link wire 6 is secured to the handle by a tightening metal tube 5.

Example 2

In this embodiment, the connecting wire is bent and extended in the threading hole 21 to form the reserved section. Specifically, the handle upper cover 211 is provided with a groove channel inside, and the length of the connecting wire in the groove channel is longer than the length of the connecting wire extending linearly; for example, a coiled arrangement or a curved arrangement.
