Abstract
Description
Technical Field
[0001] The utility model relates to a cotton ruler used for positioning and measuring mucosal surfaces, belonging to the technical field of medical measuring and positioning instruments. Background Art
[0002] At present, common measuring instruments used in clinical practice include metal rulers and angle gauges, which cannot meet the measurement requirements of fragile ophthalmic tissues such as the conjunctiva (mucous membrane), cornea and sclera, which have fixed shapes and are not suitable for compression.
[0003] At the same time, the dust-free cotton swabs currently used in clinical practice are a simple auxiliary material and wound care material. The cotton swabs currently used are also called wiping sticks, which are made of cotton heads and cotton swab rods. The cotton heads are made of medical absorbent cotton, and the cotton swab rods are divided into bamboo sticks, wooden sticks, plastic sticks, paper sticks or stainless steel sticks. Cotton swabs are mainly used in medical treatment to apply medicines, absorb pus and blood, etc.
[0004] Cotton swabs have obvious shortcomings in ophthalmic surgery, examinations, and treatments. Compared with conventional use scenarios that focus on the skin, ophthalmic applications focus on more sensitive and vulnerable mucous membranes and epithelia, which require more accurate contact surfaces rather than easy to lead to higher requirements for reducing the level of foreign matter residue. Cotton swabs are commonly used and convenient medical auxiliary materials and wound care materials, but for ophthalmic clinical use scenarios, cotton swabs have the disadvantages of easy foreign matter residue, high hardness, and limited water absorption capacity. When the cotton swab comes into contact, it may even cause secondary damage.
[0005] Eye examination and treatment place higher demands on the application of ophthalmic rulers, including more precise and controllable contact / pressure surface, more uniform and gentle ocular surface pressure, stronger water absorption capacity, and less foreign matter residue. Summary of the invention
[0006] The purpose of the utility model is: for delicate surgical procedures, such as ophthalmic surgery, it may be necessary to perform precise tissue measurement, positioning and other operations during the operation, and the current measuring instruments are difficult to meet the requirements. The utility model provides a cotton ruler for positioning and measuring mucosal surfaces, which is a ruler for measuring tissues on fragile surfaces such as mucosa. When used for measuring fragile tissues of the eye, it has the safety and comfort of ocular surface use, and has the functions of positioning, pressing and tissue isolation protection. The cotton ruler can adapt to and meet the measurement requirements during ophthalmic examinations and treatments.
[0007] In order to achieve the above-mentioned purpose, the utility model provides a cotton ruler for positioning and measuring a mucosal surface, comprising a fixedly connected cotton ruler head and a cotton ruler gripping portion, the cotton ruler head being arranged as a cone structure having a gradually increasing cross-section from the head end to the bottom, and being made of memory foam, the bottom surface of the cotton ruler head being a polygon or a sector, the polygon or the sector at least comprising a V-shaped measuring edge, and the conical surface of the cotton ruler head being provided with linear scales for marking length along two sides of the V-shaped measuring edge.
[0008] Preferably, the cotton ruler gripping portion is a gripping rod, which is fixedly connected to the head end of the cotton ruler head.
[0009] Compared with the prior art, the beneficial effects of the utility model are:
[0010] (1) The utility model discloses a cotton ruler for positioning and measuring a mucosal surface. The head of the cotton ruler has better tissue adhesion and tissue compliance. The special shape design of the head of the cotton ruler can improve the stability of adhesion and make it easier to maintain the shape of the ruler itself, thereby improving the accuracy of measurement. The bottom surface of the head of the cotton ruler is a larger contact surface, which can press, protect, and block other instruments or tissues on the tissue.
[0011] (2) The utility model provides a cotton ruler for positioning and measuring the mucosal surface, which has a small overall structure, accurate measurement, and is flexible, light, and easy to place; it can avoid secondary damage, is safe to use, and has a low cost.

[0017] In order to make the present invention more obvious and easy to understand, preferred embodiments are described in detail as follows in conjunction with the accompanying drawings.
[0018] Example 1
[0019] This embodiment provides a cotton ruler for positioning and measuring a mucosal surface, such as Figures 1-2As shown, it is composed of two components: a cotton ruler head 1 and a cotton ruler gripping portion 2, and the cotton ruler head 1 and the cotton ruler gripping portion 2 are fixedly connected.
[0020] The cotton ruler head 1 is made of a soft memory foam with a shape memory function. The memory foam is a type of polyether polyurethane foam with slow rebound mechanical properties. The cotton ruler head 1 is a cone structure with a gradually increasing cross-section from the head end to the bottom. Its bottom surface is flat and soft. As a contact surface, it will not cause damage to fragile surface tissues such as mucous membranes. Its bottom surface is a polygon or a fan-shaped, and the polygon or fan-shaped includes at least one V-shaped measuring edge. The polygon can be a triangle or a quadrilateral. The conical surface of the cotton ruler head 1 is provided with linear scales for marking length along the two sides of the V-shaped measuring edge.
[0021] In the present embodiment, the bottom surface is fan-shaped, and the fan-shaped bottom surface has fewer sharp corners. When pressing to stop bleeding is required at the same time, it will not cause unnecessary damage to fragile tissues and can better fit the shape of the eye.
[0022] The shape of the cotton ruler gripping portion 2 is aimed at being easy to hold with fingers, and a rigid material such as polypropylene plastic material is selected. In this embodiment, the cotton ruler gripping portion 2 is a cylindrical gripping rod fixed to the head end of the cotton ruler head 1, with a diameter of 2-5mm and a length of 15-30mm.
[0023] Example 2
[0024] This embodiment provides a cotton ruler for positioning and measuring a mucosal surface, such as Figures 3-4 As shown, it is composed of two components: a cotton ruler head 1 and a cotton ruler gripping portion 2, and the cotton ruler head 1 and the cotton ruler gripping portion 2 are fixedly connected.
[0025] In this embodiment, different from Embodiment 1, the bottom surface of the cotton ruler head 1 is a quadrilateral, and its shape of thin ends and wide middle can also fit the shape of the eye well. Except for this difference, the material and structure of the cotton ruler head 1 and the cotton ruler gripping part 2 are the same as those in Embodiment 1.
[0026] The above-mentioned implementation cases are only preferred implementation cases of the present utility model, and are not any formal and substantial limitations of the present utility model. It should be pointed out that ordinary technicians in this technical field can make several improvements and supplements without departing from the present utility model, and these improvements and supplements should also be regarded as the scope of protection of the present utility model.
